Mathew,

I understand that the left arm is not aligned to the plane. Nevertheless, is it possible to align the left palm to the plane and effect a sequenced release?

Yes but inorder for the entire palm to face the plane, the left wrist is dynamically bent to the degree that the left arm comes into the plane from above.

The more the left arm is above plane - the bigger the degree of bend.
The less that the left arm is above plane - the lesser the degree of bend.

If so, does a person's Grip Type make a difference in the appearance of the Left Wrist?

Yes, the amount that the left hand is turned from its vertical alignment when establishing the grip is an offset to the geometry of the wrist motions.

The more the hand is turned the more the perpendicular motion becomes a horizontal motion.

The more the hand is turned the more the horizontal motion becomes perpendicular motion.

When I talk about the 3 geometrical axis of rotation and their alignments I talk about them in the terms of the underlying mechanical structure in relation to the vertical state. In the human model - the geometry remains the same no matter what the grip type may be and is just an offset which will create different actual wrist conditions based apon it.
