Either you don't understand how FTP works or you're being intentionally argumentative. The "connection" has nothing to do with the exchange of a username/password pair. I can "connect" to your FTP server just by typing "telnet somehost 21" (or by using any other utility that creates TCP connections...netcat, etc.). The username/password pair cannot be exchanged until the connection exist. The fact that an FTP server is basically useless until the username/password pair has been exchange is irrelevant to the question of when the actual connection has been established.
