Unless I misunderstand, there is no call to bind() in the sample that 
you assert is prohibited by POSIX:

s1 = socket(..., SOCK_DGRAM, ...);
s2 = socket(..., SOCK_DGRAM, ...);
connect(s1, ...);
connect(s2, ...);

About that code, I said: "The kernel is free to use the same local 
endpoint for those two sockets as long as the remote endpoint is different."

To which you replied: "Your pseudo-code will never bind the sockets on 
the same local endpoint. It is forbidden POSIX behavior."
