case 9.1.1 part B

[palmettoref]

Hey guys. I have been reading the case book and came across this particular case and don't really understand what makes this a violation. Last year if this were to happen, it is my understanding that if a player were to lose control of the ball after it bounces off himself, we would blow it dead and readminister the FT. However according to this case, it is a violation. Why? What makes this a violation. The rules reference that the NFHS uses are the 10 sec rule for the ball to touch the rim and the FTer breaking the plane of the FT line. But neither of these actions are stated in the case. Can anybody help me make sense of this case and it's ruling?
