And what I mean by that is when you jump off of two legs you are more able to contort your body, you can use your body to protect the ball and then go over the top of the defender. When you jump off of two you can use your off shoulder, arm, and body to shield the defender away from the ball. Bron is a way more explosive one legged leaper, that "bionic left leg" as Kobe calls it and when you jump of one leg you can't create contact and shield the ball from being blocked as effectively if you jump of two.
