That's not the case. It seems that the aircraft did not send position reports as previously thought. INMARSAT and whomever (US gov't probably) were able to distinguish which satellite(s) were handshaking with the aircraft, but only to a degree that established an "arc". That arc goes North, toward the 'stans, or South, deeper into the Indian Ocean.
Even more, typically one satellite has more than one transponder and antenna systems directed to different locations, each with ellipsoid projection over the earth surface. And normally there is no distinction between informations received by different transponders on the same satellite, connected to the same system (ACARS data stream) So there is big chance, that more than one A/C path reconstruction would be possible - as in this case we have two.
