I'm pretty sure you're wrong. Mind citing a source on that the connection should terminate?

I'm fairly certain that the connection stays alive and that SSHd doesn't need to care about this, all handled on OS-level. That's why if you change IP or something like that, it doesn't "reattach" as you call it.

You might be right, however I wouldn't expect an IP change to reattach since that would be a massive security vulnerability.
