I don't think an analogy is meant to be factually equivalent, it is meant to convey meaning. I perfectly understood the meaning of the parent comment, even if it is technically inaccurate.

We aren't trying to understand minds or caches, we're trying to encourage a practice that has little to do with the inner workings of either.
