> But it could also be the case that the client first connects to "c", disconnects, then connect to "b" using the token obtained from "c" from a different address. In that case, the attack becomes concerning even when the client is not behind a NAT.

This is an address validation token. It is coded for a particular client address. The client will not use the token if it has migrated to a different address.
