Based on that state diagram, I see two possibilities:

1) both parties are calling connect() at the same time. Since this requires knowing both IP/Port pairs ahead of time, both parties would have to bind() to specific IP/Port pairs and then exchange that info with each other (if not hard-coded) before calling connect().

2) one party is calling listen() and then sendto() with the listening socket while the other party is calling connect() at the same time after calling bind().

Either condition is not common in socket programming. You never have two clients connect()'ing to each other, and you rarely if ever send data on a listening socket, you wait for accept() to return an established endpoint first and then you send data with that instead.
