The heart of the matter is that all of the cell phones in the plane are in a wonderful metal enclosure, with limited capability to connect to ANYTHING outside of the plane, except for attenuated signals through the small windows.
What they are talking about is, since they've already put WiFi in the planes, is having a cell transceiver IN the airplane that multiplexes all of the calls into a single satellite link on the plane. That can use the same channel as the WiFi. Your cell phone is not going to be connecting to a terrestrial tower or a satellite. Your cell phone is going to be connecting to the onboard unit which, to your phone, looks like a normal cell tower.
