Did They Get This Right?

Was this correct?

I think you mean "held ball". Was the throw-down a result of two people holding the ball or was it a direct throw-down? How soon is "immediately"? Was it as the whistle was blowing or clearly after?

As Adam said penalize the foul and do not switch the arrow.
