The video is about congnition specifically, and not necessarily about communicating with analogies.

What you’re describing is exactly why I strongly recommend avoiding analogy when communicating: Don’t tell me what a thing is like, tell me what the thing is. This forces really thinking about how to describe the thing precisely and succinctly. (Edit: The listener will make their own analogy.)
