alternating possession rule-seems quirky

I'll give this a shot. Let's say you have 90 seconds to go in a tie game. Team A has just been awarded an alternating possession throw in. Team b only has 3 team fouls. Now, team a is handed the ball for the throw in and, under you scenario, the arrow has changed. Team b fouls. No harm done as they are still not in the penalty. Except team a has just lost their ap throw in rights. The next ap possession goes to team b.

I am not sure what the problem is with the above scenario. Why shouldn't they lose the ap rights? if the ball gets in-bounded and they get fouled a second later, now they lose their ap rights, why should it be different if the ball never gets in bounds?
