Yes, it is involved: statically scoped vars are not affected, while
dynamically scoped vars are affected, which is why the text says
"dynamic".

I guess I don't understand how "the words basically speak for
themselves" leads to a difficulty.

Sadly, I still fail to grasp what kind of change to the wording could
address the problem because I still don't really understand the problem.
Maybe you could try to rewrite that bit in a way that you find more
clear (or if there's still some part of the behavior over which you have
doubts, then I'd be happily to try and explain it further).
