I suppose you could be right, since there is probably no one simotaneously doing TCP/IP releases/renews on either of the networks I deal with in large.
To elaborate on my point, though, DHCP does assign IP addresses by MAC addresses. If the local computer (in reference) has a lease, it sends the DHCP server its MAC address, which is validated. If the server verifies the existance of the lease, it assigns it the previously designated IP address (this is why none of the IP's on my network change, even though I've been using the same DHCP server for over a year).
