I tentatively agree with your final sentence. While Camron makes a good point, I think the point of the rule is to give the thrower an unfettered throw. Whether the player is legally OOB only means you don't add a DOG warning to the mix, IMO.

I guess that I'm harsh. To me the rule is now very clear. You foul a thrower, it is an intentional personal foul. Period.
If you do so on the OOB side of the boundary plane, it also constitutes a delay of game warning. I don't care if the player was there legally or not. The contact is still illegal and the rule is crystal clear on the appropriate penalty.
