Webu/IdealisticAfrican has it right. The datum is a theoretical reference, but the physical surface will not have the flatness of a perfect datum. You'll need to tell the machinist just how close to the datum the surface needs to be. All three measurements are non-redundant. The first flatness tells you how flat the surface at the datum needs to be.
