not quite sure what you mean by the other.

Bleeding out, when combined with techniques like unusual camera angles, foreshortening, perspective tricks, clever panelling etc., can add a lot to the feeling of depth of a drawing. In the pic I quoted, it's much more visible on the top panel than in the bottom one, because her legs are extended towards the viewer. Combined with the bleedout, it adds a slight "3-dimensionality" to the art, don't you think?
