Its not just anchor text that is affected when the link has a named anchor. It is also pagerank. The testing I performed indicated that two links to page.html on the same page pass only as much page rank as one link. Links to page.html and page.html#anchor both pass pagerank. When this happens, its unclear to me where this pagerank "goes" for the link with anchor on it. It may only apply to a section of the page.
