This trick is particularly useful for rendering things that have somewhat of a hierarchy, but aren't implicitly hierarchal. Like a table of contents for a HTML page, targeting the various header (h1-h6) elements. They're not (generally) descendents of each other, and parsing them is simpler to just go as a list of items with a depth.
