Please, see the thread starting on:

http://mail.gnu.org/pipermail/emacs-devel/2002-February/006028.html

Consensus seems to be that user code shouldn't trust the save-match-data
to be consistent across function invocations, unless they're basic
primitives or "functions that have the spirit of a general-purpose
facility". (FWIW, I don't know if file-expand-wildcards matchs that
definition :)
