I'd say there is some magic. Possibly.No, because in fact you can. There is nothing magic about an in-addr.arpa domain.
If an admin were granted the authority for a /25 worth of space, then you can't just delegate that part of the in-addr.arpa domain. That's the RFC Joe Abley cited.
A /24 can be delegated (assuming we are talking about 255 addresses, from .0 to .255). Perhaps, and this is weak speculation, the ISP in question is not used to SWIPing /24 and has an institutional policy of using RFC 2317 in all cases.
As far as the DNS protocol goes, there's nothing different between the forward and reverse. But there are differences in the conventions used for placing data.
