The reason why Brett was seeing all these being the same domain is because Brett's search URL had &num=100 in it, therefore showing 100 results per page.
I think it has been long around that Google moves up results from the same domain when more than one result is shown.
If you change Brett's URL to be &num=10 then you get much more varied results on the first page.
I checked google encrypted subdomain (SSL) and the ordinary google.com domain and they are pretty much the same, hence the difference is in the num parameter and not whether the search was on encrypted domain or not.
