Jump stop?

[fan]

I am clear that when a dribbler controls the ball with one foot on floor than jumps off that foot and lands simultaneously on both feet they cannot pivot. However, when a dribbler executes the jump stop but they get control of the ball after jumping off of one foot and then they land with a jump stop. They still can use a pivot foot right? If this is true it seems like it would be hard for an official to judge whether or not they had control with the foot on the floor or off the floor to determine if they get a pivot or not.


Thanks
