I don't know, I haven't been in a pro boxing gym in 15 years.
But, I don't think the word "confuses" fits in this discussion, it's not a matter of people confusing anything with anything else. It's just terminology. As for pro boxing gyms, I've been in many. And in those gyms, not all trainers use the exact same terms. But there was never any confusion, because it's all in context with what's being done at that time. And people weren't there for words and terms, they were there for training and prep.
I've been in and around boxing since I was a kid, trained with a lot of folks. I'm completely familiar with the term "return", have used it myself, but don't really any more. At a certain level, returns and counters kind got lumped together. Counters are also sometimes called "intercepts", and outside of the boxing gym, some of us use the term "time framing" to encompass all of it.
In 79 I had dinner with Tommy Hearns. I think he was 22 and 0 at the time. For three hours we talked boxing and fighting in general. It was a lot of fun. In that conversation I don't think either of us used "return', we just spoke it as counter. I trained many times with Ray Leonard, sometimes we'd use the term "return" but most times we wouldn't.
So, maybe it's a generation thing. Years ago we would describe you as a popcorn, no disrespect intended, it was just used in a descriptive sense, but that's not used much any more. Look, bro, I know you want it to be THE terminology used by everyone, but it ain't.
