Not really floating, but less grounded if that makes sense. Two things that induce this buoyant state is when the palm is supinated either upward or outward, or the foot or feet turn out. Sounds like something out of Crouching Tiger, Hidden Dragon but it works. This comes from Chinese Kempo by the way, which is something Master Bellman incorporated or perhaps re-incorporated into jujitsu. I'm glad you asked about this Ian, because I just realized that both of these positions have implications for lifting. Supinate the hand for pullups and they become easier. Turn out the feet and the squat becomes easier. I know there are other kinesiological factors, but go figure.
The throw you describe is one of several variations I know from judo as a well as jujitsu. Using mushin ryu's 26 principles the hand/wrist technique you describe is primarily about body misalignment, the neck, head and spine in this case. I think of the body as a stack of blocks and when you push one or more out of line, the stack collapses. So with the body. You can accomplish the same throw with a palm heel strike directly up and under the jaw, shoving the head sideways, or shoving your right arm over their shoulder in contact with the traps. All of them work well.
