I'm not absolutely sure, but I believe this was one of the things that was fixed early on. At least, in the very early days you'd end up with duplicate entries if you crossposted and then imported, and that got fixed. It think in general it ought to sync rather than duplicating or overwriting. Maybe there's a faq somewhere.
