Since the engines of the P-38L and the Seneca are turning in opposite directions, the p-factor of both propellers are compensating each other. Thats why aircraft with counterrotating props are made: they are easier to fly!
Try yourself: Get the P-38L in the air and fly full throttle straight and level, open the property-browser for controls/flight. I need a right aileron deflection to keep the wings level. If I reduce power to idle, the aircraft turns sharply to the right with that aileron setting. This should not happen on aircraft with counterrotating props.
