You have to explicitly remove that IP address from the
interface.  Downing an interface just means that this
specific interface will no longer send or receive packets.

However if you still have other interfaces up and they
receive packets for IP addresses assigned to the downed
interface, they will still be received.

IP addresses are assosciated with the host, not specific
interfaces.
