Note, the wires that operate each window motor on Fords(all as far as I know), they are the same wires electrically at each switch for that window.
So the RF switch on the driver's door and the switch on the RF door, they both are connected to the RF window motor. They are specifically all grounded when no switch is pressed.
Each window switch diverts power from a power wire going to the switch, to one of the two motor wires, while also cutting the connection of that wire to ground. That means that each motor has a ground that is unchanged by a switch, and the other wire is rerouted to the power source wire.
Thus, since the pairs of wires at the main switch are the same electrically as each other door switch, the module will allow each pair of switches to do the same thing. I think you could place the modules all in the LF door, or in the doors you want affected.
Don't let my window wiring confuse the subject, as I have two master switches, one on each front door. That was my mail vehicle, so I wanted control of all four windows from the RF seat. I had to add two relays to each door(window wiring), to isolate the motors so that the master switches wouldn't be fighting each other.
It's been four years since I did that wiring, but I still know how the circuits work fairly well.
