Enabling SO_REUSEADDR by default means you'd allow another socket to bind even when Windows doesn't.
Can you please find a piece of documentation which proves your words? Because I don't have this information and I believe you are not correct.

The second bind call is supposed to fail with an INUSE error when no options are set on either socket.
