Nope, the foul would only end the attempt if that foul prevented the shooter from releasing the ball. In the case being discussed, the ball was released. That attempt(try) now would end when the throw was successful or when it was certain the throw would not be successful. And it was certain that the throw would not be successful as soon as A1 touched the try again after that initial try left his hands.

The concept of the airborne shooter touching the ball before a second attempt at a try is considered by rule to end the first try and also make the ball dead with that touching at the same time.
