You are of course correct. In North America at least though, I do not believe many people are confused. The term “buffalo” is used much more commonly than “Prarie Bison”. I am not defending it but it is ubiquitous to the point that everybody knows what people mean when they say “buffalo”. If somebody said “buffalo” to me, I would assume they meant bison ( unless I had additional context ). If they meant Asian or African buffalo, I would expect them to say “water buffalo”. Again, I am not arguing what is correct. I am commenting on what I think people, as a group, understand.
