In this case samba does not need to check all files.

   Please note that enabling this can slow down listing large
   directories significantly. Samba has to evaluate the ACLs of all
   directory members, which can be a lot of effort.

Yes, it is.

        /*
         * Never hide files from the root user.
         * We use (uid_t)0 here not sec_initial_uid()
         * as make test uses a single user context.
         */

        if (get_current_uid(conn) == (uid_t)0) {
                return True;
        }
