What happens with the Stevie Johnson checkside technique? They only recently modified the rules to allow players to start off the line and move perpendicular to the goals without being called play on as long as they didn’t cross the line of the man on the mark. They could even do this after the siren without being called play on. Is this now play on?

Banning it would cost goals so I’m predicting the AFL will find a way to finagle their way into making an exception.
