Ah. Wasn't aware of that as:

http://manpages.ubuntu.com/manpages/lucid/en/man8/dhclient.8.html

The  client  normally  doesn’t  release  the current lease as it is not
required by the DHCP protocol.  Some cable ISPs require  their  clients
to  notify  the  server if they wish to release an assigned IP address.
The -r flag explicitly releases the current lease, and once  the  lease
has been released, the client exits.

If the client is killed by a signal (for example at shutdown or reboot)
it won’t execute the dhclient-script (8) at exit. However if  you  shut
the  client  down  gracefully  with  -r or -x it will execute dhclient-
script (8) at shutdown with the specific reason for calling the  script
set.

doesn't seem to indicate otherwise. Note: not arguing the point, just
trying to understand :-)
