To add to all the correct replies above....

Consider if instead of A2, it had been B2 that caught/touched the ball while OOB. Would the violation be on the thrower or the player who touches the ball while OOB? If it is a violation on the thrower, I, as a defender would try my best to get a foot OOB and touch the ball. Of course, this is not the case. It is a violation on B2. A's ball at that spot. Since there is no distinction between offense and defense on OOB violations, it must, in the original scenario, be a violation on A2 and the spot is where A2 touches it.
