I've seen him with crossed arms plenty of times. When I've seen him do it, he's sometimes listening intently. To me, it seems like a slight subconscious way to control an urge to talk, maybe? Which means he probably has a lot to say on the subject. Or it could be a bit of a strong stance, he feels strongly about something and he's not budging etc. There's all kinds of stuff you could read into it. Body language experts think they're always right, but they are not. They give good insight, but not everything is so cut and dry. (not talking about you, OP! lol.)

You are right. He does it when he's not changing his mind or to keep from arguing with someone.
