Since the page is already loaded into the cache by the time the 
markup is processed, it's a bit faster to do:

    global $PCache, $pagename;
    if ($PCache[$pagename]['=auth']['edit']) {
      return 'You have edit rights.';
    } else {
      return 'Read only.';

I don't immediately see an error with what you're doing, however,
so I'm not exactly sure what's going on.

Are you running your site with $EnableIMS set?  If so, you
might be seeing the effects of the browser cache.
