I remember reading somewhere that this fix is "officially" to fix a shifting/acceleration delay when slowing down to slow speed of 3 - 10 mph and then trying to accelerate from this slow speed. This is just one of the symptoms of the throttle lag when pulling away from a stop. Maybe the "official" symptom there are stating the update is for is more of a safety issue then just pulling away smoothly from a stop. Either way, both issues are fixed with the update.
