Correctable Error
 

I need some help with understanding the answer to a Refresher Exam answer.

A-1 is fouled. The scorer informs the official that it is the 10th foul on team B. the first free throw is unsuccessful. The second free throw is successful. When B-1 has the ball for the throw in, the scorer informs the official that team B has only commited 9 team fouls. The Official cancels the last free throw and resumes play with the AP procedure. Is the official correct?
The Answer key says ( NO ).

This same play is used in the 2008-2009 case book page 11. 2.10.1 situation D. If I use this situation on the above play, I would say the official is correct, therefore my answer would be (yes).
What am I not understanding about this play, any help would be great.

Nevada will be responding to this shortly, I'm sure.

There's been some concern that the new case play is incorrect, as discussed previously on this site.

Since play is resumed at the point where it was interrpted to cerrect the error, and since B had disposal at that point, B should remain with the ball (for the throw-in)

The NCAA case book uses the same ruling as in situation 2.10.1D NFHS case book.
