No.... that is exactly one potential issue.    An entity wishing to move
their networks around ought to bear costs of their moves;  the RIR
such as ARIN should not be subsidizing an entity's choice to move
out of region and continue to keep everything nice and convenient for
that resource holder by incurring extra costs against the fees paid by
other still-in-region members  to help facilitate the operations of some
small number of  'wanting to move out'  resource holders;   This
is not in the interests of the regional community whom its ARIN's
mission to serve  to be in a position of continuing to provide
a Reverse DNS service to the entity that moved out after they
are no longer an ARIN customer,   And  "fragmenting" in this
manner is exactly what this forces upon ARIN.

The kind of Reverse DNS Zone that is simplest for RIRs to have
software, systems, and process to manage -- is one where all the
NS delegations are predictable and match up exactly with database
entries created by customers  linked to a direct allocation or assignment.

And the requirement to maintain additional, extra nameserver delegations
for "transferred blocks"  means  designing, developing, or maintaining,
systems, algorithms, and management processes which involve
more ARIN staff time being used to operate,  and a
greater minimum complexity  than the simplest form
(which would meet the simpler requirements of each delegation
maintained by an ARIN customer).

Aside from the administrative burden that ARIN now would have to
maintain an entirely additional set of delegations and database entries
which are for out-of-region usage on transferred out V6 space,  and
have processes and people to  update these entries from time to time:
when the  end user's downstream nameserver addresses change.

To keep such a transfer in effect and reverse DNS working properly:
ARIN (and therefore other ARIN members) would effectively have to
also bear an ongoing cost on behalf of the foreign registrant in perpetuity
without compensation for the services,  because that organization will
be cancelling their relationship with ARIN and/or no longer be paying
any maintenance fee for that block of addresses.

Meanwhile....  ARIN continues to have to maintain DNS servers with
computational and bandwidth resources allocated
to answering queries that come for the reverse DNS range of THAT block
transferred out and maintaining a set of nameserver delegations in the
reverse DNS zone for the "transferred out" address block in order to do so.

And the VOLUME (total number of reverse DNS queries per day) per
block  varies with the usage of that block,  size,  etc,
so it is non-predictable.

ARIN likely needs that entity as a customer while delegating reverse
DNS to them,
in order to be be able to charge maintenance fees to compensate ARIN for
costs of providing the  service of answering the reverse DNS
Nameserver  queries.
