Throw-in violation?

[zm1283]

D1 men's game tonight. H10 makes a three point try. V player picks the ball up (At his disposal) and tosses it to the new Trail who is about to start his count. Trail catches the ball and tosses it back to the V player. V player doesn't muff it, but drops it onto the court after he has caught it. He picks it up again and tosses it back to the Trail, who in turn tosses it back to him again and then he completes the throw-in.

I don't know if I just missed something or what, but I was shocked that they didn't call this a violation. I just figured in D1 men's games they would call the violation if the thrower tossed the ball to the official after it was at his disposal, and if not that, the thrower dropping it in bounds after it was at his disposal a second time.
