Jump stop vs "up and down"

If he decides to shoot while in the air, that is legal. But if he lands on both feet at the same time, that is also legal. By rule, it does not matter if he intends to shoot or not.

Can you explain.

I don't follow either.

Suppose A1 raises one foot as if to start a lay-up, sees that the shot will be blocked, and puts the foot back on the floor. That's not illegal (I don't htink), so I don't see why an otherwise-legal jump stop would be illegal.
