Team Editing

Does a copyeditor ever work with a partner or partners on a manuscript?

I once did a "team translation" (English to Japanese), where each team member was responsible for translating a certain portion of a lengthy manuscript. The difficulty was that the final translation had to read like a work of a single person, and my teammates and I had to make sure that we used the same translations for certain terminologies.

Is there such a thing as a "team copyediting"? If there is, what precautions would the involved copyeditors have to take?
