For transmitter on the northern track to create the same time of arrival and Doppler effect at satellite as a transmitter on the southern track, it would have to know in realtime the exact perturbations upon the trajectory of the receiving satellite and instantly change the transmitting frequency to mimick its effects.Jeff does mention things like wobbling satellites and the doppler effect, but that's way above my pay grade. I have no idea. Jeff was part of the Independent Group, so I don't think he'd make any fundamental mistakes. You might find the answer on his website.
He does say that different planes had different satellite comms units, each having different ways of calculating the BFO: some were fakeable, while other units were secure.
