My thought exactly.
Also:
"Incoming connections and datagrams are distributed to the server sockets using a hash based on the 4-tuple of the connection—that is, the peer IP address and port plus the local IP address and port. (...) This eases the task of conducting stateful conversations between the client and server."
It is presented as an "implementation detail" so I guess one should not be surprised if it stops working this way sometime in the future? :)
