No, that's not correct Gimp. I'm not sure how you think II.M
interferes with XVI.J.2, but they are consistent.
As quoted by Josh, you can break contact with the pivot spot, so long
as a "new pivot is established at the same location".
Are you suggesting that you can only stand so long as you keep the
same pivot at the same spot on the field? That isn't correct. The rule
is pretty clear that you can establish a "new pivot". I think you're
reading into XVI.J.2 that you are allowed to only 'reestablish the
same pivot'. That's not the case.
You're right that II.M says the pivot is the part of the body in
contact with the single spot on the field through the whole
possession, but XVI.J.2 is an exception which is more specific.
