No, sync'ing does not include the UID.
The UID is server-depended and may change across IMAP sessions, reflected 
by the change of UIDVALIDITY of the folder.

However, Dovecot stores the UIDs in dovecot-uidlist files in each mailbox 
folder, so you could patch offlineimap to synchronize that file with the 
UIDs from the source IMAP server. But I think will get you other trouble.
