Matthew, as you can also see from the second picture in NCBlades posting this bar engages the top back part of the blade and replaces the stop pin used in other folders. If I'm not mistaken, this idea is copied from Bob Dozier, who made a folder with a so called double integral lock, meaning one bar engages the blade on the top and one on the bottom. In a milder form called Dozier lock, a huge liner which engages the blade over the entire back.
I don't want to open a can of worms here, but whenever I hear Farid, I get the impression that he copies other peoples ideas and overbuilds them. Not my idea of creativity or honorable craftsmanship. Therefore, no Farid for me, ever.
