Even without a music theorist telling you that point 3 is wrong, it just makes the music harder to read. Of course, the reason is what the theorist would give, but it highlights that he isn't really reading music. He's reading notes. He hasn't learned what those notes mean in context. It's like he's learned how to sound out written words in a foreign language but doesn't actually know what any of the words mean. Thanks for the link, it gave me a good laugh.
