Multiple Area 0's due to acquisitions, large internal network, how does OSPF discern the area 0's apart logically?

Title pretty much states my question, how does OSPF interpret seeing routes learned from different Area 0's within the same AS that is split up logically by other area's in between. I would imagine OSPF would think there is a routing loop, correct?

Our wanted Area 0 is going to see the cost to get the other source that is advertising area 0 routes as high seeing as how it is geographically disperse from it. Will that impact any routing logic?

Area 0 (New York) - Area 1 - Area 0 (Boston [Intended Area 0])

Pardon me if this is a stupid question.
