It is because this links are a shortcut to advanced search with some parameters. Don’t think it is a bug to show such page when nothing found, but maybe it is confusing sometimes.
Just for me there is only one confusing thing. There should be some link to home page near with the return link.

That is strange ‘cause this seems to be an active topic and there was a new post :) but still… lol

Since yesterday all seems to be fine maybe it was hick-up in chrome.
