I see a single quote both before and after sessionurl.

$vbulletin->session->vars['sessionurl'] is the name of a vBulletin variable. In the quote in your original post, this is not in any quote marks at all, so it will be assigned its proper value when the script is run.

The ending single-quote is after the ? of member.php.

I really, really suggest picking up a book on PHP if you're going to dissect vBulletin scripts.

But, in short, the quotes are paired properly, because if they weren't the script would fail upon execution. It doesn't fail, ergo the quotes match.
