Semantics are important. What's not important is correcting a term that was good enough for its intended purpose and derails an otherwise fruitful discussion into nitpicking about the meaning of words being used. In this case I don't think it was really a big deal either way. Discussion about the major 3rd in the video wasn't really harmed much, and a few mildly interesting posts about semantics resulted.
