Player/Team Control during "simultaneous possession"?

It doesn't help that some officials will comply.

I was trying to find solid ground in the rules, but was unsuccessful.

If a player is dribbling or holding the ball, he has player control and his team has team control.

If both players are holding the ball, it's a held ball. You can't have traveling. Neither team can be granted a timeout and after you whistle the held ball.

Who cares whether the coaches likes the explanation or not? Call what you see!
