My point is that setting the saddle too far forward relative to the saddle rail clamp may affect a rider's balance on the saddle, regardless of what motivated said rider to slide the saddle forward in the first place, e.g., to decrease reach, to sit more forward relative to the BB, etc. The extent of this effect (of course) depends on the rider's weight and where exactly the rider sits on the saddle. You had mentioned positioning the saddle to prevent "falling forward"; this is taught in the two videos below, which I follow to set my saddle fore/aft position relative to the saddle rail clamp.
