Having  multiple  PTRs  for the same IP is not a useful strategy. Most
round-trip  checks  will  use  the  first  PTR returned (and the order
cannot be guaranteed).

That's  not  because  you  have  multiple  PTRs, but because _any_ PTR
exists,  and also because all the PTRs will pass a PTR-to-A roundtrip.
You're not getting anything by having multiple PTRs for a single IP.
