Hmn ... is the IP even released? I never really thought about this, but my assumption was that the clients and the assigned IPs are cached till the pool is full. So when a client that was already connected normally gets the same IP and only if there are no more "free" IPs the firewall takes an IP from the "pool" of not connected devices.
I think everything you've said is the same thing that I've noticed in my testing. As long as the client is still present in the 'Previous Users' table they'll be assigned the same IP address each time they connect. I've never had a time were I've not had a big enough IP Pool, so I can't really speak on what happens if there aren't anymore 'free' IPs.
