I can't stress enough the importance of NOT having your toes point OUTWARD as you found in the many google images. However I also disagree with a low stance being a "practical" device. It is very good for training however. I believe the horse stance is used to condition yourself so that you are better to move around in all sorts of stances when in true combat. It is comparable to slow movements in TaiChi that condition your body isometrics. However in practice is done at full speed.
