Do you mean the (funcall search base-re) part?  If so, then no, it
doesn't need save-excursion because it just calls re-search-forward,
which doesn't move point when the search fails.

Actually I think neither order is quite correct for all cases, because the
regex we construct is currently too lax: if we're searching for a method
definition with no specializers, it also matches definitions with
specializers.  So ISTM that this needs some more work to get right.
If no one beats me to it, I'll look into it when I have some time.


Best,
