ok that it is fine. I try to understand your concerns.
you say : "Router-X interface that points to Router-2 is still up and Router-2 interface that points to Router-X is still UP too.
But, Router-2 receives routes to Router-X from OSPF cloud and that route points to interface that point directly to Router-X.
This route is redistributed to Router-2 from Router-X via link to Router-X - Router-1. "
Both routers R2 and RX will have the subnet in their own Router LSA and their LSAs are flooded in Area 10 NSSA.
From Area 10 ABR (10,0) R1 point of view it can see the subnet reachable via R2 or via RX or both depending on OSPF cost.
R2 will receive RX's Router LSA but it will not use the info about that subnet because it is also a direct connected link with AD=0 better then OSPF's AD=110.
So even in this case you don't need to worry about this.
If the two routers advertise a different subnet for the link where they cannot build the OSPF adj then each will install the subnet advertised by the other but the routing will go via R1 on the NBMA link for the missing adj.
Again, this is not a connectivity problem but can become a perfomance issue if a lot of traffic is going through the NBMA instead of using the direct LAN link
Use debug ospf adj to troubleshoot the missing adj between R2 and Rx.
