Zac sets a custom_wp_title() but never sets the $sep. Where does the "|" separator come from when the default is '»'?

So Zac set the $title and returns it, but never sets $sep. Where does the "|" separator come from? According to the WordPress Docs the default is '»'.

O, it's set in the index.php… So because the $sep is not set it takes ('|', true, 'right')?

So technically leaving the $sep unset in the function custom_wp_title() makes it available to set in the index.php with 

<title><?php wp_title( '|', true, 'right' ); ?></title>.

And setting it $sep in the function custom_wp_title() overrides the manual set in index.php.

<?php 
function custom_wp_title( $title, $sep ) {
global $page;
// Add the site name.
$title .= get_bloginfo( 'name' );
// Add the site description for the home/front page.
$site_description = get_bloginfo( 'description', 'display' );
if ( $site_description && ( is_home() || is_front_page() ) ) {
    $sep = '&#x2602;';
    $title = "$title $sep $site_description";
} 
    return $title;
} 
add_filter( 'wp_title', 'custom_wp_title', 20, 2 );
