Update: Just found out that The Silver Turk's official script (though not words spoken out loud) uses language like puppet Mary for duplicates. So I guess there is somewhat of a precedent for that sort of naming (Zygon Kate Stewart), though still not an in-universe one, and this particular source certainly does not use it.
