Who is saying that the analogously named models are equivalent the analogs themselves? Analogous terminology and metaphors exist so that people can ease themselves into a deeper understanding of a subject. I agree that some people can incorrectly draw grand conclusions from a simple name, but that doesn't mean the people who use these "things" with these "names" only understand their mechanisms on a superficial level. Seriously, good luck explaining any model without introducing an analog that we, as humans, can relate with.
