I am reposting Canon Gregory Hesse's video at the time (19:10) that he directly answers and corrects your error. You only need to listen for a couple of minutes. It won't hurt.

Good research, Drew. I'm going to have to listen more to Fr Hessee; i've never heard him speak before.
Cantarella,
He also makes a great point, one which I have been making, is that, as a matter of law, the roman missal is NOT a mere disciplinary act. It is much, much more. Listen starting at 29:35.
