This applies quite generically to coaching as well: if the person you're listening to uses a certain word to describe something, continue to use that word yourself instead of trying to paraphrase it. In that sense, you're sticking to one word for a concept, but the word is given to you by someone else. And by using their terminology and not your own refactoring, you are making sure that you're not distracting them from their own thinking.
