Really. Loopback interface is still interface and can be listened on. PuTTY doesn't care if it's loopback or not - it simply listens on this interface and forwards traffic wherever it's configured to forward. How the remote side forwards it further is a different question. It may be not forwarded further at all if you're talking to sshd on db host directly.

See above. It's not mandatory to have remote sshd to be configured this way if sshd runs on db host and you are accessing it directly. If you are using it as the gateway then yes, it should be configured like you say.
