If you took at look at this you would notice its not dealing with that spider system. Its dealing with the $show['search_engine'] variable defined in the init process using

PHP Code:

// conditional used in templates to hide things from search engines.
$show['search_engine'] = ($vbulletin->superglobal_size['_COOKIE'] == 0 AND preg_match("#(google|msnbot|yahoo! slurp)#si", $_SERVER['HTTP_USER_AGENT']));
