MediaWiki messages are special, as they're used by mediawiki. The defaults are in the MessagesXX.php files. When you haven't edited the MediaWiki namespace the page doesn't exist, so it shows the default at the php files.
I assumed it was something like that and it makes the "create" tab correct, although the documentation doesn't reflect this. I suppose I could edit the documentation, though. ;)
