I'm not sure the image does say it all.
If this is architecture is derived from something AWD like a subaru, the engine supplies power to the front and rear differentials through a third open differential (drawing on left). For example, if you just took the central driveshaft off, you end up with a freewheeling flange (for the rear diff) and the front wheels wouldn't get any power.
If you put an electric motor on the open flange (drawing on right), you'd be pushing power from the motor through the centr diff. you'd have to have the ICE and electric motor delivering torque at the same time in order for the car to move. If the motor was delivering more torque than the ICE, I think it might actually turn the ICE backwards.
If you welded the center diff, it might work as you envision.
