He gave the two examples at Honig's when presenting this change:
Receiver touches out of bounds, leaps, controls the ball, and either lands in bounds or legally bats it to a teammate. Previously live ball (could be foul for illegal touching depending on how he went OOB). Now incomplete pass.
Receiving team player jumps from in bounds, controls the ball, and lands out of bounds. Previously free kick out of bounds. Now B's ball at the spot the ball crossed the sideline. He felt this was consistent with the player standing near the sideline and touching the ball before it goes out of bounds.
RR felt this was a logical definition for out of bounds and in bounds. We all know Alf has argued this should be the interpretation of the previous rule, but that's not the case. Even though this is an editorial change, it is a change in the rule and not just a change in philosophy.
