Good advice! It is physically impossible to be out of alignment when you stand upright in your stirrups as any leaning forward/tipping back etc will unbalance you and you won't be able to stay upright. You should be able to stand perfectly straight without holding the front of your saddle at halt, walk, trot and if you get really good, canter.
