No it does not. This is different thing. This is about managing duplicates on multiple syncs.
Imapsync seems to keep track of UID -> MAIL mapping for server A and UID -> MAIL mapping for server B so that on multiple runs it does not sync the same messages again. However it does not use the same UID -> MAIL for server B as is originally on server A. And that is the problem.
