Understood on specifics. But can you comment on the general ARIN policy on the topic? My understanding was that once a legacy resource was transferred , it was permanently removed as a legacy resource.

As noted earlier, general ARIN policy is as follows - 

Those who received IPv4 address blocks by InterNIC (or its predecessors) prior to the inception of ARIN on 22 December 1997 are legacy resource holders, and continue to receive those same registry services for those blocks (Whois, reverse DNS, ability to update) without any need for an agreement with ARIN.  This has been provided without any fee to the original registrants (or their legal successors) as recognition of their contributions to the early Internet.

Some legacy resource holders opt to sign a “legacy registration services agreement” by which ARIN provides specific and well-defined legal rights to the registrant – this is the same RSA as other ARIN customers, but ARIN caps the total annual maintenance fees that are incurred by legacy resource holders.  An RSA is also required to receive services that the community has funded the developed since ARIN’s inception, such as resource certification services. 

Thanks!
