No, rsync is particularly dumb in that respect.  The safest thing would be 
to back up the reflogs first (e.g. with rsync), then repack and then clone 
(the clone will transmit the objects referenced by the reflogs, too).  
Note: the same holds _not_ true for a simple fetch.

But then, you usually do not want to back up reflogs anyway, since they are purely local and not visible to anybody else.
