That's indeed what it meant, but this restriction was lifted sometime
after 24.1, see
http://help-gnu-emacs.gnu.narkive.com/uspqRdsq/surrounding-lexical-variable-reference-in-the-body-of-defun
and http://stackoverflow.com/questions/12026137/emacs-the-code-in-the-body-of-a-defun-or-defmacro-cannot-refer-to-surrounding-l.
Updated patch to remove that sentence.
