I remember Kelly talking about this in the past, and if I remember right, it was supposed that it helps to push off the big toe with the feet and therefore involve the glutes better (not sure what the actual mechanism is, but that's what I remember).
Me personally - I use it when I jump off two feet without the ball in hand. I feel like I can gather more energy this way, like it gives me better rhythm etc, hard to really explain.
