Why global first about update_user_option()?

    function update_user_option( $user_id, $option_name, $newvalue, $global = false ) {
	global $wpdb;

	if ( !$global )
		$option_name = $wpdb->get_blog_prefix() . $option_name;

	return update_user_meta( $user_id, $option_name, $newvalue );
}

    I read the source code and I don’t know why global $wpdb first.
    Why not global after the if ( !$global ) condition? It it working faster, right?
