It won't be any better or worse for your link on a page like that.
The server is set up so that when you go to a directory, but don't specify the page, the default page will be displayed. Typically the default is "index.html". You can change this through .htaccess. Making default.html, index.php, or whatever.asp be the default file in a directory.
So when you specify a directory, but not a file, the server just displays the default file without indicating it in the address bar of your browser. If the site you mentioned is using php, try adding "index.php" to the end, or "index.html" if it is a static site.
Structuring internal links this way gives a lot of flexibility. You could, for example change the technology your site uses to serve pages (going from .asp to php) without losing your
PR.
Again, this kind of structure won't make a difference one way or the other.
