Google is failing to follow and enforce their own rules. How can a company run five sites using a different scheme on each one offering the same product to the penny but not get filtered?
It's keyword spam and they don't care.
I've also seen similar cases, but not with five sites. My own competitor runs two sites, with identical niche products. He even goes so far as to use the exact same adsense publisher id on each site. Now you'd think Google would spot that and drill down to find the dupes. No such luck. You can give these blackhats enough rope to hang themselves, but even then, Google just won't whip the horse.
