With the DCT the car has to be in neutral at idle or else it would stall. The same as letting out the clutch on a manual transmission car at zero vehicle speed. If you had a torque converter the engine is separated from the wheels via the torque converter and allowing for the slippage cooled by fluid trapped inside the gearbox. Since the mechanism on the DCT is mechanically similar to a manual gearbox.
