Tobias described it properly, there's more what you can and should do.

sorry, this is irelevant and also not a problem.
Multiple A/AAAA records may point to the same IP and they don't need
coresponging PTR. In fact there SHOULD be only one PTR for each IP.
The FCrDNS only applies IP->host->IP, not the opposite way.
Too many people still get that confused.. Still occasionally find PTR's
with a dozen or so records.. silly, and causes UDP retries when too much
data..
People.. ONE and only one PTR record is needed.
