Quote - Which may raise some questions.  Does the order of the rotation parameters in a pose affect anything?

I don't think the rotation order makes any diffrence in a pose file, I think the figure applies them in the order they are in in the cr2, irrispective of the pose. I just think that, I have never done any tests to prove it, and what goes for a pose used as a normal pose, may not apply to a pose used in the WD.
