It can even show a different organization - a differently "faceted" way of organizing the information architecture - for instance, content by application rather than content by product name.
An html sitemap of this nature also has an SEO purpose, in that it gives search engines another signal as to what the priorities of the various pages are - another reason not to link to every page.
