Speak for yourself. Some of us are both.

and as computer scientists respecting other science branches is a duty. Using the expression "isomorphic" in that context is just confusing.

That's a fair point, but "context" is the key word. Using "isomorphic" incorrectly in a mathematical context would be one thing. But borrowing the word to use in a largely unrelated context seems fine to me. And it isn't like this is the first time a word has been borrowed and used to mean something "similar or related, but not quite the same". I'm pretty sure this has even happened inside other scientific disciplines, although I'll grant you that I don't have an example at my fingertips.
