Multiple sessions from the same source port

Hi, I've a question on socket programming (I'm a bit rusty on this). I'm reading an article on NAT, which mentions a case where a client opens two sessions (to two distinct remote end-points), but from the same source ip:port. How is this possible? I thought every time a client program open a socket to a remote ip:port, the OS will automatically associate the local endpoint with a differrent port number?
