You didn’t just do that. You said that the teacher’s words don’t match their meaning.
I do not need an explanation of the fact that human language is imprecise in general
Explanations may be a poor way of promoting beliefs, but belief in that fact would discourage your claim that the teacher’s statement has a precise meaning.
I think newerspeak’s take is pretty good. It quite late (and rather temporarily) that you switched from discussing lack of clarity, especially the need to learn a new idiom, to discussing what is bad about the phrasing. (except that I strongly object to newerspeak’s use of “wrong phrasing.”)
You can (like newerspeak, with the well-chosen username) think that the choice of idiom has bad consequences. I might agree, but only contingently on my political beliefs about education. But to say that an idiom is wrong is a category error.

I don’t understand. That was the phenomenon in question.
