With the scores locked at 8-8 in the 72nd minute, Cummins initially ruled the Canberra Raiders would be awarded a fresh set of six tackles - believing Roosters fullback James Tedesco had spilled a bomb - and signalled as such.
He quickly changed his mind, however, calling out 'last tackle' multiple times as the Raiders' attacking raid died with Jack Wighton tackled with the ball.

Wighton said the call was "massive" and that he didn't know Cummins had reversed his decision - but Annesley said he was right to do so.
"I had a look at four different camera angles of that. I think that the ball did come off the shoulder of a Raiders' player (rather than Tedesco)," Annesley told Channel Nine.
"The referee does call six more, but then immediately gets a call from the assist referee and one of the touch judges that it was off a Raiders' player.
"He immediately corrected that call and called last tackle and called last tackle four more times before the play actually break down.
"It's very disappointing that the game has been mined in controversy after that initial six again call.
"But ultimately, I believe the decision not to give six more tackles was correct and had they not corrected that decision, I would probably be standing here talking to you now about the fact that a try may have been scored in the next set off an incorrect decision where six tackles shouldn't have been awarded."
Former Parramatta star Peter Sterling said that the players may not have heard the revised call.
"When you're in the heat of battle, a player will see the signal, he won't hear anything else. He won't hear the verbal change of decision," Sterling said.
Certainly Wighton felt aggrieved by the decision and said he was 'just following the boss' when he held onto the ball.
"Everyone seen it with their eyes," Wighton said.
"I probably would have tried to get a repeat set or something if it wasn't six again.
"I was just following the boss. That is his decision and that is something I won't blame the game on, even though it is probably a big patch in the game."

Johnathan Thurston has added his two cents to the blunder which changed the entire momentum of this grand final.
After watching the vision post-match, which clearly shows Ben Cummins signalling 'six again' before Jack Wighton is tackled with the ball, Thurston said he would be 'shattered' had he been in the Raiders' position.
"I'm dumbfounded by that. You can hear the referees calling it six again, six again," Thurston said.
"And then changing the call on the run. It's not a good look. It is not a good look at all.
"I would be pretty shattered if I was the Raiders. The next set, Tedesco scores and wins them the match.
"Really, it is not a great look. As a team, you want to take the referees out of the equation and win the game being a consistent footy team, but, yeah,
huge, huge call."

After the most controversial grand final in recent memory, fans have been slammed for booing Clive Churchill medal winner Jack Wighton.
Wighton was adjudged the best on ground, despite playing on the losing side, after a powerhouse display that included a barnstorming first-half try.
However he was roundly booed as he walked on stage to accept his award, with the Roosters fanbase pinned as the troublemakers.
The the match officials are now being booed!
They were poor. It would be interesting to know the breakdown of which fans were booing.
You could argue the Roosters – who have the bulk of the fans left in the ground – had very little to boo about!
Wighton joins the small list of players winning the Clive Churchill medal on losing teams.
There's a smattering of boos from the Roosters fans. Classless, that.
He's short on words in his acceptance speech and understandably so.
"I'd just like to thank all our Raiders' fans for turning up tonight," Wighton said.
"We love you as always. Very, very proud of our boys.
"This is the numbest feeling I have ever felt. Congratulations to the Sydney Roosters who got us tonight.
"Hopefully we will see you again in another dance like this. Thank you, everybody."

Sia Soliola has been named the Ken Stephens medal winner.
Hollywood icon and South Sydney owner Russell Crowe has slammed the refereeing performance in the Sydney Roosters' GF victory.
Crowe described the win as a 'horsesh**t result' and an 'embarrassment' for the game.
They've done it! The Roosters become the first team to go back to back in a unified competition since the 1993 Brisbane Broncos.
It wasn't without controversy – both of their tries came off the back extremely questionable decisions – but what a famous victory.
They prevail 14-8 and send Cooper Cronk out a winner.
Raiders fans will have every right to be furious though. The referees will be in the spotlight for their huge blunders.
