On the one hand, I would leave the guy to the range in that situation. If I'm using a bunch of real estate on the steel area of my range (perhaps doing moving / multiple target drills) I really appreciate the courtesy if people leave me to the range and go shoot some paper elsewhere.
With that said, I don't own the range and if someone came over and wanted to use half the steel, I'd greet them and adjust what I'm doing. Heck, if they walked up and said "are you using all the steel" I'd say "no, feel free", even if I had been. I think it's good etiquette to leave people alone on a range if possible and I appreciate the same. If someone asks though, it shouldn't be an issue and wouldn't be for me.
Bottom line... Guy was an a$$ (but I'd have left him alone to start with).
