AI will generally err on the side of slavishly copying any reference. I'm having this problem at work lately. Teammates will be asked to implement a new module for <new data integration> into the codebase, and they'll just point Claude at it and say "integrate <new thing> into this codebase" in one shot and what it will do is create a function for function clone of the first data integration's client, down to implementing copies of the private utility methods.
