There is more to a choreography than the interfaces involved. To take the WS-Chor example, if I only have a bunch of interfaces I have no choreography. What the choreography defines is the connection of interfaces to one another (in the sense that, for instance, one interface describes the response to a message associated with another interface), the correct sequence of messages, and the change in internal state of the various services involved.
