I think this is about the site: command only returning supplemental results in Google when "pages from the UK" is selected. I don't think its anything to worry about, it is happening with all the websites I have tried, including Google! Smaller sites I have checked return primary and supplemental when I do the web search, then return only the supplementals when I do a UK search. I doubt its effecting search, but hopefully something that will be fixed soon...
