 connection, QUIC processes that packet accordingly. Note that more than one
 connection ID can be associated with a connection; see {{connection-id}}.
-If the Destination Connection ID is zero length and the packet matches the
-local address and port of a connection where the endpoint used zero-length
-connection IDs, QUIC processes the packet as part of that connection.
+If the Destination Connection ID is zero length and the addressing information

Would making the text more alarming help?  s/subject to the limitations described in XX/though this makes connections fragile as described in XX/
