The head is not "motionless" in the strictest sense, because it does rotate around its vertical axis, similar to what the torso is doing. One only has to notice where the nose is pointing to see that the head rotates.
Correct. The photos in 9-1 and 9-2 clearly illustrate that Head Rotation about an axis -- Johnny Miller called it a little 'chin swing' -- does not violate the concept of Stationary Head maintaining its position in space.
