Including $ORIGIN in the body of the zone file is usually a bad idea,
and almost always unnecessary. It's definitely a bad idea to do it twice
in a row with different $ORIGINs, and a worse idea to include that same
thing multiple times.

Sorry, it's not at all clear what you have to change. Are you saying
that you have to change the hostnames for all the PTRs in the zone? If
so, and you're doing the same kind of pattern-based hostnames you could
simply use $GENERATE. Something like:
$GENERATE 0-255 $ PTR dynamic-172-58-0-$.example.com.
You can read more about $GENERATE in the ARM.
