While there is no RFC requirement that they match is there any reason
not to make them match (the above records don't match) given that is
the intent of the IN-ADDR.ARPA namespace?

well, I don't know any now...
Instead, I agree with another poster who suggested a mismatch or
absence of this data in the DNS is good input to a scoring system,
but not good grounds for outright rejection.
That's highly depentent on the receiver system, and its policy. It's
really useless to comply about it here.
The point here is that the reverse records were simply invalid without
any reason.
