Yes it does, or the address would be unreachable for anyone.

The hidden patch (or the noarp module that I use) is hiding a MAC address. It
means that an arp request on the IP wil be hidden by ANOTHER MAC address (the
one of the VIP of the director).
I did not really understand what you tried to do, but you can't bind the same
IP on two different interfaces on the same machine. In fact, I don't know if
you can or not, but I can't figure out how the packets would be routed. I don't
think that the kernel would duplicate the packets to the two interfaces. It
will probably forward the packet to one interface, regarding routing priority,
or something.
If I had to do what you try, I would just bind the service your pollux
application use to a specific port.
Hope this helps,
François.
