OSPF with Nexus 5k pair

I am wondering what the correct way of doing this is to prevent extra routes in the routing table or if this is as expected.

Router A - 10.1.0.2/24 and 10.1.1.2/24

Router B - 10.1.0.3/24 and 10.1.1.3/24

Both routers have an L3 interface for the above addresses and are running HSRP with the .1 as the virtual IP in both networks (so 10.1.0.1 and 10.1.1.1).

Now Router C is setup as an OSPF neighbor with A and B on the 10.1.0.0/24 network. So router C is learning 10.1.1.0/24 and it has two route table entries, one for 10.1.0.2 and 10.1.0.3.

My question, is this expected? Or how would Router C learn 10.1.1.0/24 but have the next hop be 10.1.0.1 the HSRP interface? I feel like it shouldn't be doubling up on the routes as it is asking for odd troubles, but not sure how I'd limit it?

TIA!
