If the engine is above X rpm, it doesn't need the starter to restart, just the ignition - If you EOC you'll sometimes key back on at around 250rpm and the engine will re-fire. I'm guessing there's a window between around 250 and 0 rpm where the ECU waits for a 'zero' RPM signal before engaging the starter. There are also extra sensors on the flywheel to help the ECU synch up sooner at part crank revolutions.
I have two factory S/S cars and their literature only speaks of 'reinforced' ring gears, special batteries and larger starter motors. They're still brushed DC.
The sales brochure of the Renault speaks of 'programmable' stop/start. The owners manual makes no mention - it will be interesting to see what that means when the factory ordered vehicle actually gets here in two months.
