Correctable Error Question

[FrankHtown]

I thought, up until this case book ruling, that they clear the lane, let A shoot the second shot, then give B the ball at the point of interruption, since there was a change of possession.

Now, if the timer was on his/her toes, and didn't start the clock after the missed free throw, I could see going back and shooting the free throw with players on the lane.
