You're correct that A1 did not violate. However, if it were an AP throw-in, the arrow would change since A1 did complete the AP throw-in.

4-42-5 says: "The throw-in ends when the passed ball touches, or is touched by, an inbounds player other than the thrower."

In the situation in question, the ball is touched by an out-of-bounds player, no?
