Sure, but the author is advocating that you compose HTML this way. It would quickly become a mess of nested elements with zero visual indication of hierarchy.
The DOM is a tree, with nested elements. Losing that information doesn't get you anything but tag soup (which is, oddly, what the author suggests this style is supposed to avoid)
