Hi Gem! While that site is interesting, it too, is misleading IMO. The heritage of the American Pitt Bull includes many of those that are also pictured. The "American" Pitt Bull is not a pure breed. IDK if the documentation against ownership of pitt bulls is reserved for "American" only...but the entire "breed."
See similar photos of pitt bulls (as in the above site) and heritage of the breed.

I lived by someone with a pitt bull for many years, and the dog was sweet unless he saw a stranger, then he was very difficult to control
