Can someone explain the umpiring blunder in the NRL GF to someone (me) who does not know the rules. Six again?

And how it led to the game deciding try...

Simple enough, on the 5th tackle most teams kick and try and score or get good field position. 

On the 6th tackle the ball is automatically turned over to the opposition. 

If during any point an opposing player makes a deliberate play at a ball ie, tries to intercept a pass etc and they touch it but the attacking team gets the ball back they get 6more (tackles)

The ref yells this and waves his arm over his head.

Now, one ref did this in the GF, the Raiders player then took the tackle expecting to have another set of 6, but the other ref said no, gave the ball to the Roosters who then went up the other end in a couple of plays and scored the go ahead try.

If the first ref didn’t call it, the raider player may have put a kick into the end zone or even had a kick at goal for a 1pt score to take the lead. 

Im not 100%on the rule if both refs call different things but the Raiders has all the momentum and in that call/non call it was turned on its head.

Thanks. That's very helpful. I think I've got it.
