I know I only have 3 posts at this forum, as of this writing, but I know a lot about article directories and how Google, Yahoo and Bing index the articles that are published to them.
The directory you mentioned above is notorious for not showing up in the backlink checker tools. Whether they are counted or not, nobody can really say.
I do a lot of article marketing and watch thousands of articles ranking in the SEs every day. That being said, I do not submit to that directory.
Good luck and keep writing!
