Iptables is not perfect and even when you use DROP rather than REJECT a port scanner can tell that DROP is in use by doing a SYN scan. If a server is on the port the SYN will get an ACK, otherwise it gets a RST. So the bad guy knows that he is getting nailed by a DROP rule and there is a live server being protected by the DROP rule. So he sets up an infinite loop trying to connect.
He hopes you will someday have a problem, wonder if iptables is causing it, and try dropping iptables just for a few seconds. Or maybe you will change your configuration and do a quick "service iptables restart". Most iptable configs allow ESTABLISHED connections to persist so once he connects... he is in.
