The hands and belly button going back while the hips start to go forward is when disassociation happens early. The hips breaking away from an active stride gives you stretch and core contraction capabilities when you want. There are many ways to get forward yet. I have explained but one. I know of two or three. The hinge and the back knee are the others I know of. It’s style imo. But you gotta get FYB if you’re gonna have a chance to adjust and hit multiple pitches/speeds.
Look at the cadence of his strides. The length might be the same or not. But the timing(s) are different. The stride initiates launch.
