Back court violation exception for defender?

[billyu2]

I'm sure this question has come up before but I cannot remember the ruling:
9.9.1D A1's throw in near the division line is deflected by B1. A2 jumps from his f/c, catches the ball and lands in b/c = violation. But what if B2 jumps from his f/c, catches the ball and lands in his b/c? Does B2 benefit from the defender exception resulting in no violation or does the ruling in 9.9.1D apply where it says, "The exception granted during a throw in ends when the throw in ends and is only for the player making the initial touch on the ball?"
