Ah, so lexical binding _is_ relevant to this, in the sense that
lexically-bound variables are _not_ affected!  Then please say that,
maybe in parentheses or as a footnote.

And please don't use "statically scoped", because we don't use this
terminology anywhere in the ELisp manual.  We always say "lexical
scoping".

I hope now it is more clear.
