w3 uses same anchor text - different landing pages?

Why is the W3.org having "Archive" as anchor text for different landing
pages? Also, it is observed that the "title" element is different in all the
similar anchor text. Isn't this an accessibility problem?

Seen at http://www.w3.org/

Note: I've accidentally posted this message at html-tidy too, i apologize
for the same.
