Why WordPress not logout after I have close my browser?

I used this code in wordpress functions.php, to auto logout customer/user after payment in woocommerce or close the browser

function logged_in( $expirein ) {
   return 6; // 6 in seconds
}
add_filter( 'auth_cookie_expiration', 'logged_in' );

function wp_logout2() {
    wp_destroy_current_session();
    wp_clear_auth_cookie();

    /**
     * Fires after a user is logged-out.
     *
     * @since 1.5.0
     */
    do_action( 'wp_logout2' );
}

function wpse108399_change_cookie_logout( $expiration, $user_id, $remember ){
    if( $remember && user_can( $user_id, 'administrator' ) ){
        $expiration = 604800;// yes, I know this is 1 minute
    }
    if( $remember && user_can( $user_id, 'editor' ) ){
        $expiration = 604800;// yes, I know this is 1 minute
    }
    }
    return $expiration;
}
add_filter( 'auth_cookie_expiration','wpse108399_change_cookie_logout', 10, 3 );

/**
 * Bypass logout confirmation.
 */
function iconic_bypass_logout_confirmation() {
    global $wp;

    if ( isset( $wp->query_vars['customer-logout'] ) ) {
            wp_redirect( str_replace( '&', '&', wp_logout_url( wc_get_page_permalink( 'myaccount' ) ) ) );
        exit;
    }
}

add_action( 'template_redirect', 'iconic_bypass_logout_confirmation' );

A part of this code it’s for increase expiration time to administrators of wordpress or other kinds of user

function wpse108399_change_cookie_logout( $expiration, $user_id, $remember ){
    if( $remember && user_can( $user_id, 'administrator' ) ){
        $expiration = 604800;// yes, I know this is 1 minute
    }
    if( $remember && user_can( $user_id, 'editor' ) ){
        $expiration = 604800;// yes, I know this is 1 minute
    }
    }
    return $expiration;
}
add_filter( 'auth_cookie_expiration','wpse108399_change_cookie_logout', 10, 3 );
