The 'double clutching' here was not in reference to shifting gears. It was referring to bump starting by letting out the clutch gently just till the engine turns over and starts and then pushing the clutch back in quickly so as not to force the motor to spin up to a high RPM in a few miliseconds.

In many vehicles, simply letting the clutch out all the way to start the motor, all in one move, will cause a jerk and rebound situation that I find most unsettling.
