both feet leaving the ground at the same time is impossible because that would then be considered hopping. I believe the author meant to convey that both feet are airborne at the same instant in time so the speed is maximized as one foot propels forward the body and the other foot lands to continue the motion and prevent falling as the force of gravity must be resisted during the forward motion of the ostrich.
