The result is the car goes forward but the movement that leads to that is not horizontal (or the shock would never move). If you were to sit your car on the bench and screw the tires to the surface and give it the gas, you'd watch the pod start to lift at the nose, fully extend the shock and finally pull the front tires.
So the axle centerline ie bearings in the pod where axle is attached is above the pod pivot so pod pivots forward; balanced +/- by motor climbing force. Probably why it is possible to see more on power steering by increasing spring and/or increasing droop. For 17.5 stock I definitely feel more on power with more spring. I could also see the motor climbing the axle in mod or 10.5 and lifting the front tires.
