Let me rephrase that. A lot of waypoints have the "or Above" constraints. As per the FCTM, if we make the last "or Above" waypoint a hard altitude, it usually permits a normal deceleration for flaps and gear extension. If you leave it as an "or Above" waypoint, if the winds are not exactly as planned or if the ATC give late descent clearance, one can easily end up a bit high. I'm not saying they programmed it wrong. All i'm saying is thay if you are not monitoring the descent properly, you could end up a bit high.
