It seems the owner of these sites has found a perfect recipe to get that topic highly ranked - this is a great find for you to reverse engineer the recipe (but obvious a real pain in the neck that you can't compete).
I know from experience that google would have picked only one of these sites to rank, and push the others way back, if they had the same owner (same ip range, whois, google account etc). Seems either google have changed that, or this webmaster has done a lot of work hidding who actually owns the sites.
How do you know for sure that it's the same owner?
