Hi Paul,
If I understand you correctly, you are describe medial deviation of the wrist, that is, in the case of a vertical fist, the little finger side rotating downwards.
I have noticed that many Japanese kenshi use this action. The action is whiplike, at the instant of impact. From a biomechanical viewpoint, this activates the triceps and thus gives a similar effect to rotating the wrist horizontally. My understanding is that the whiplike medial wrist deviation amplifies the power and percussive effect of the punch. I have been working on this actionsince returning from Japan in September and am very pleased with it. I do not agree that it increases the risk of bending the wrist on impact.
