The difference is in the speed delta. To get the car moving, you're starting with an 800 or so RPM/difference (engine speed 800 RPM, driveline speed 0). To restart the engine at speed, the difference is around 2000 RPM (engine speed 0, driveline speed 2000). So that 1/10th of a second is probably about equivalent to 1/2 a second of getting a car moving.
