It isn't.

Because it should.
To explain: in DR mode the director does not see the entire TCP
transaction (it only sees one side, the client side) since the
realservers respond directly to the client.
When one of the realservers is "local" then full state can be kept, so
the director knows how many active (ie. open in TCP terms) and inactive
(ie. in TIME_WAIT or FIN_WAIT state) connections exist. This looks to
the inexperienced eye as a real imbalance in load distribution but it
may not be the case in reality.
You'd be much better off using the other statistical options to ipvsadm:
ipvsadm -Ln --stats
ipvsadm -Ln --rate
These will give you a much better view of how many actual connections
you're handling.
