 At any time, endpoints MAY change the Destination Connection ID they send to a
 value that has not been used on another path.
 
-An endpoint MUST use a new connection ID if it initiates connection migration as
-described in {{initiating-migration}} or probes a new network path as described
-in {{probing}}.  An endpoint MUST use a new connection ID in response to a
-change in the address of a peer if the packet with the new peer address uses an
-active connection ID that has not been previously used by the peer.
+An endpoint MUST NOT reuse a connection ID when sending from more than one local
+address, for example when initiating connection migration as described in
+{{initiating-migration}} or when probing a new network path as described in
+{{probing}}.
+
+Similarly, an endpoint MUST NOT reuse a connection ID when sending to more than
+one destination address.  However, if an endpoint receives packets from a new
+source address with the same destination connection ID, it MAY continue to use
+the current connection ID with the new address.

Thanks for doing that Eric.  It looks good to me.
