Three points or two?

[Illini_Ref]

A1 makes a throw in from the division line. The throw is high and A2 jumps from the top of the key (behind the 3 pt. line) in an attempt to catch the ball. The throw touches A2's hand and deflects into A's basket. Two points or three?

I believe it is two, but I am just trying to get other opinions. There is a case in the case book, but in that case the pass is touched at the free throw line.
