The comment replies plugin uses its own table to store the comment replies. Because of this, the replies are not included within the comment feed.
To keep any classes from interfering with styles already within the blog theme, no classes were added to the comment replies by default. This can all be edited by styling the comment replies through the options page. You can see an example in this screen shot: http://www.flickr.com/photos/cnp_studio/2245871285/in/photostream/
