You're quite right, I read "not just for beginners" as "just not for
beginners".

And you've correctly identified that I am a little worried about this
sort of thing, since I read an article about preventing shoulder
injuries, where the author said this rolling up off the bottom is one
way to dislocate a shoulder. He said he would write another article
about how to prevent that, but it hasn't appeared yet. I really really
don't want to dislocate a shoulder.

You could dislocate your shoulder putting a jacket on...

If you think about the action involved in rolling and that sweep out and
down, it is a very short step to sweeping it too far back and everything
going per shaped anyway. I've known a few people pull back and shoulder
muscles when rolling and getting it wrong.

I'd imagine that in punting the danger would really be in flowing water,
where your paddle stuck in the bed of the river/ lake/ sea, remains fixed
and your boat and you get swept forwards placing your shoulder in a
dangerous position. The usual motto applies, if it hurts stop doing it. In
this case, if it starts hurting, let go. On a river if you go over in 2
feet of water and can't get back up, there is a good chance you could lose a
few teeth - at least. I'd try punting.
