Depends on how you said it. Sometimes people that are trying to help come off as elitist because of how they word it. I do think there's nothing wrong with letting people figure out the mechanics on their own, though. It's what I do. I don't learn from watching videos or following tutorials for rotations. They do absolutely nothing for me. I learn by experience. Perhaps this guy was like that and the leader knew it. Perhaps the leader felt you were pushing the issue too much. Just say it once and then let them be.
