Nope, that's not how it works. You seem to misunderstand the events. The original MS eyes are actually removed and replaced by the MS eyes of another person, which means that the removed eyes can be preserved somewhere. And the combined pattern of the EMS is the result of the interaction between the user's chakra and the newly-transplanted MS eyes of the previous user. There is no "merging" of the two sets of eyes or something, the original eyes are literally taken out to implant a new pair of eyes from your relative afterwards.
