Understood. When the torque converter is not in lock up mode, the engine revs are free to change somewhat independently of vehicle speed, and the change from a higher to lower torque converter speed ratio provides a torque boost. A torque converter will always be more "responsive" to sudden engine power changes than a manual because of this effect.
