Nowhere in my instrument training because we had no autopilot did it say to monitor the descent. It said do it to the next altitude. I know the new guys use automation because of their expeience level so tend to rely on it more than us old guys. Hope they figure it out before the next event. The next one might be like Buffalo if they don't get their act together. Just learn to hand fly like us old pilots and you will be fine. Relying on automation works sometimes.
