It's needed -- the data transferred from the IMAP server to the client
is impractically large if one were to do a complete resync each time.
The client keeps tracks of read/marked/etc messages, too, and just sends
a QRESYNC command to the server, which means "tell me everything that's
changed since last time".  This is vastly more efficient.
