What is important is that the ball remains live when the second FT attempt is missed and that the clock starts upon the tap by A2. This is the point at which the correctable error timeframe begins. Since the live ball now passes through the basket for a goal it becomes dead and the error must be fixed at this moment. As you note, once the ball is deemed to be at the disposal of Team B for a throw-in and becomes live again, it is too late to correct the error of awarding unmerited FTs.

Thanks for the catch. I knew my conclusion had a slight flaw in it, but was too lazy to pull out my books.
