The flaw in this argument is that transmission of RR73 does not ensure
reception of RR73. "Exchanged" requires both transmission and reception,

Hi Andy,
the requirement usually is that both operators are assured that they
have completed the QSO. A rapid QSO followed by the other station
calling CQ or calling another station straight away is often all that is
needed to be sure that an RR73 message has been successfully decoded and
the QSO logged at the other end.
