David,

Please see RFC 791, page 24:

     That is, there must be a mapping between internet host addresses  
and
     network/host interfaces that allows several internet addresses to
     correspond to one interface.

This implies that any single IP address corresponds to a subset of  
the interfaces
on the router (typically only one).

The binding of an IP address to an interface has been argued to be an  
architectural
misfeature, but it is certainly a long term accepted facet of the IP  
architecture.
