Yep, you’re correct. I got to that bit and thought that can’t be right. It’s obviously wrong. If you rotate a semantic vector, you change the semantics of it. You don’t want that.

Makes me wonder if the whole thing is just slop.

Is the rest of the article correct?

Anyone suggest an alternative article?
