It's redirected with an HTTP location header (you can watch this in any
packet sniffer or in-application HTTP protocol display such as the Live
HTTP Headers extension on Firefox).

If you mean, why's it redirected and how is the target URL determined:
the title given in the URL is non-canonical (none given where Main_Page
expected) so the canonical URL is formed and sent as a redirect target.

Article view URLs are constructed from $wgArticlePath. Please see
LocalSettings.php and DefaultSettings.php.
