It's my understanding that rdnis comes from the phone. When someone forwards their calls, the phone sends back the 'Moved Temporarily' message to Asterisk. Asterisk interprets the SIP message and passes rdnis, dnid and extension back to the dial plan when it re-enters it. It tries to dial the new extension. My original DIAL() command has 'g' in it... which I guess is what causes Asterisk to re-enter the dial plan as it does, and try to find a match for the new extension.
