This gif is a knee lift with good posture maintained. Look at the hinge in the back leg. Many on here say that is a “no no”. If you have good posture and pick your front knee up towards belly button without coming out of posture hip coil takes care of itself. No rearward movement
the only thing that I see different is a gathering of his weight back or down if you like. First . Then a knee lift. Not just a picking up of the leg. That wouldn’t be optimal imo.
