He got past the defense, but the guy made a great defensive play and the Mocs still had a great look to win on the rebound. MUCH, much easier to get a good shot in that situation when operating in the flow of the game rather than giving a team a chance to set up a defense. They can trap, switch up defenses, take away your best option, and so forth. You only call timeout in that situation if the offense looks confused or disjointed. This idea you call a timeout in that situation is a fallacy which continues to persist in the minds of fans.
