User blog comment:Tormented Sufferer/Deleted MediaWiki pages' links/@comment-2200849-20130720154706/@comment-1929113-20130720155637

The page displaying the default content is intentional. You will also notice that the pages are no longer on the wiki, seen at c:okami:Special:AllPages?namespace=8. The pages still display the content because the mediawiki pages are to override their default messages, not to originally define them.
