I have plugin which redirects myweb.com/wp-login.php to custom login page myweb.com/member-login/

I want to check if current page is either wp-login.php or /member-login/ but does not work. code below

( ( $pagenow !== 'wp-login.php') || ( $pagenow !== '/member-login/') )

Any clue why?

UPDATE:
In mean time a have created

$uri = $_SERVER['REQUEST_URI'];
( $pagenow !== 'wp-login.php')||( !strncmp($uri,'/member-login/',strlen('/member-login/')) ) 

and check is OK
