Any rule in any sport that requires the umpire to read a player's mind is a ridiculous rule. This includes deliberate out of bounds and deliberate rushed behind. There used to be a similar rule in hockey (could still be) that if a defender hit a ball out there was a different penalty according to what was in the defender's mind.
These sorts of decisions should be taken out of the umpire's considerations. eg last player to touch the ball before it goes out concedes a penalty regardless of his intention, wave the flags for a behind before the kick-in etc
