If I understand you correctly, NS1 and NS2 host the same zone with
different information.  And, you want NS2 to consult NS1 for the
difference.  That will not work.  Once a name server loads a zone, it is
authoritative for that zone and will consult no other name servers for
information within that zone.  In other words, if a name server hosts a
zone it assumes that the zone is complete and no other information about
that zone exists anywhere else in the name space.  There is no way to
stop this behavior.
