Intentional foul on throw-in

[AKOFL]

So we all know the rule about making contact with thrower or the ball on a throw-in. Intentional foul for contact on the thrower and a T for contact on the ball. I'm sure it's been discussed before, but don't you have to break the plane before contact can happen. So you would always have a delay of game warning before any of these other sits. happen. was having a disscusion with some other officials and was wondering your thoughts. Reasons for thoes other rules if you know of any. thanks
