Created Unassigned: Composite.Tools.LegacyUrlHandler on site with multiple hostnames [2105]

When I run /StoreCurrentPaths.aspx on a site with multiple hostnames I get a list where pages on the current site is listed without hostname (like /mypage) and pages on the other sites is listed with hostname (like http://www.contoso.com/mypage).
Is this intended?
Do I have to run /StoreCurrentPaths.aspx from all hostnames?
