Well, I'll defer to Brian. His source address explanation is cleaner and more intuitive than my zone ID explanation. It also has the benefit that it matches what is in the addressing architecture document. I'm not sure, though, that Brian's explanation is consistent with the following line in the scoped address architecture: "Each interface belongs to exactly one zone of each possible scope." Based on Brian's explanation, it would seem like the interfaces of router B are actually each in two subnet-local zones, and router B is using the source address of received packets to choose between them.
