Also, to me at least, the throw-in exception makes sense in that the exception applies only during a throw-in. And, according to the rule, the throw-in ends when the ball is legally touched in-bounds, so it makes sense the exception ends at that moment as well.

No, I agree with all of that, now knowing that the rule protects only the first to tip. A2 catching a tipped ball is NOT protected and hence a backcourt violation occurs. If the ball tips from his hand (first to touch), that is not considered control, and he is protected into the backcourt without a violation. Again, I am learning this application, but that is the way I read the casebook and rule book.
