The AFL love implementing what they do in the US, so...
In the NBA and NHL when reviewing buzzer-beating events they look at where the ball/puck was when the clock hit 0:00.
If reviewed the same way this would show the correct decision was made.
I like how you have no idea how a timer works. When it goes to 0:00 it's really 0:00:99. There's still a whole second left when it shows 0:00.
