True, and if the fly is just a simple ragged, dubbed scud there really is no top or bottom so who cares if it drifts on it's "side?"
Just remember, if you do tie like illustrated, heavily weighted on one side of the hook, the fly invert and drift weighted-side down. So really, as the picture shows, lashing a humpback of lead on the top side of a curved scud hook will make a bug that drifts inverted - hook up, and body curved up as well. So you have to tie your scud back in on the "bottom" or underside of the hook. Or leave it off altogether and see what the heck happens.
