Maybe one of the more knowledgeable people on here could answer that.
My take - the level sensor is towards the front of the sump.
Under heavy acceleration the oil moves to the rear of the sump and lowers the level around the sensor thus momentarily cause the level light to come on.
Note that the oil pick-up is in a well within the sump so this will always remain full.
Also note that the oil pump displaces a fixed volume of oil for xxx rotations of its impellor. What does change is how quickly it moves the oil as the revs increase.
