I would say that playing it safe is the best way forward here. Uniqueness of content is pretty highly valued, so having the same article appear on a directory and on your own site at the same time may not be a good step. What you might consider doing is having two "versions" of the "same" article. Same topic, same title even, but make the one on your website longer than the submitted one.
You could make the same points, but change the way you say things, and you can even include something on the article directories to say "you can read more about this topic at ...". It says a lot about you as a writer if you can show that type of versatility.
