SMH...do you agree that her right foot is the pivot foot and she lifts it to take a step with her left before releasing the ball?That might have been me. But, they are both legal
That is traveling.
On a layup, gather 1-2 is not because the second step establishes the pivot. In this case, it's gather, step with the left, establishing the right foot as the pivot. Then the pivot foot lifts to step with the left again without/before shooting the ball.
This is not a difficult concept.
