This is a PHP based feed parser which means that the content of the feed articles will show up in your sites HTML code. (this is not true of javascript type parsers)
This means that search engines will recognize the content of these  article snippets as new content on your site each time it spiders your site.
Search engines love sites with fresh content and rank them higher than static sites. To see the difference between the two, hit "View' then 'Source' on this HTML page. Now go to PHP page and look at the source code there. You will notice the RSS feed information has become part of the HTML code.
