hostnames can have more than three components, e.g. "www.ox.ac.uk". So it's either biggest to smallest: "com.google.www" or smallest to biggest: "www.google.com".
google.com.www is in neither ascending or descending order.
www.google/stuff works now that we have generic TLDs and .google is a TLD, but before that it ignores the possibility of google.net and google.org. This may not be a problem for a unique trademark like google but not all domains are trademarks.
