I dealt with this a lot at a hosting company I worked for. This is almost certainly a .htaccess file that is set to only redirect based on referrer. It is normally under several hundred blank lines, to make it look empty to the casual observer.
I can't access the linked url (it's https: http://news.ycombinator.com/item?id=3575029), but as far as I remember, if an HTTPS page links to (or redirects to) another page that is not on the same domain, the HTTP REFERRER field will be empty.

It can't be.

Google's redirect is not an HTTPS link, so it sends referrer (see my comment below).
