In a sentence

[Scrapper1]

The clarification that came out a couple years ago was that the loss of control that ended a dribble could occur due to any type of contact by an opponent. Previously, the rule stated that the dribble ended when loss of control was caused by an opponent batting the ball, specifically requiring an intentional use of the opponent's hands.

Loss of control has always been needed (for this part of the rule) to end the dribble. Now, however, any type of contact by an opponent can cause the loss of control, and thus end the dribble.

So in the original question, since the official judged that the dribbler never lost player control, the dribble did not end. This ruling would have been correct even without the clarification.
