That's what I remember. Also checking the code :

    if ( msg->via1->rport || (msg->msg_flags&FL_FORCE_RPORT) ||
    received_test(msg) ) { ADD_RECEIVED }

So, received it added if rport was present in VIA, if you did 
force_rport() in script or if the IPs are different


    if ((msg->msg_flags&FL_FORCE_RPORT)||
            (msg->via1->rport )){ ADD_RPORT}

For rport, it is added if rport was present in VIA, if you did 
force_rport() in script

So, I cannot see how rport would be present without received...
