The scene drawn by Steven in this video is occupied by figures but in the finished drawing would all be men. There are no boxed men or boxed women really. I suppose you could make some boxes smaller and others bigger but don't get hung up on details, they need to be simple forms while giving enough visual information to make it look like a figure in space. if you or any artist wanted a less boxy look as a foundation for drawing a more feminine figure this artist could use circles and ovals instead of boxes. But this is actually harder then it sounds. When drawing a scene in perspective, unless you've done this hundreds of times it will be very hard to draw a figure in perspective using circles and ovals. Without cross contour lines those circles and ovals have no "depth", they dont look like spheres they look like circles. The boxes help the learner see the figure in perspective much easier. Drawing figures from many different perspectives really gives the student a working knowledge of thinking/drawing in 3d space.
