Yes there is truth to that. The vast majority of RE/Gotti dogs will be American Bully style. That is a larger pit (anywhere from 70-over 100lbs) Usually with shorter legs and more of a barrel style body than one with a nice tuck. Their faces tend to be a little more mastiffy looking, round instead of square.
However not ALL RE/Gotti dogs -will- look like that. I have two RE/Gotti/Other dogs and both of them have nice legs and good body porportions. They will be bigger than your average
APBT and my female is a little more lippy (droppy lips), but in General anything that comes from those lines is deemed an American Bully (AmBully). If you want to learn a little more about them you can check out the American Bully Kennel Club at
http://www.abkc.com (it might be underconstruction)
They can be and are generally still registered with the UKC as
APBT's though the UKC is taking baby steps to disuade this from happen. And all that Purple Ribbon means is that seven generations have been registered with the UKC. (although to register a dog with the ABKC you have to have a 3gen ped from another registery, it gets confusing lol)
Hope that helped a little.
