The MD-11 autothrottle system (ATS) reduces to idle at 50ft agl independently if the airplane is on a correct pitch angle and landing flare. During crosswind and/or downdraft conditions it’s highly recommended to control the power to avoid a situation where airspeed and rate of descent can increase with the throttles at idle. At or below Vref elevator control is almost nil and a bounced landing is unavoidable. A proper recovery is: increase thrust until GA, if required, and keeping pitch angle not more than 7.5 degrees nose up with wings level. However with an extremely high sink rate an unpredictable consequence, like a wing or gear break up, can be really expected. Additionally, LSAS is unserviceable below 100ft, and pilot has complete manual elevator control.
