I really don't think that feature works. I've been meaning to do more reading up on it and actual testing, but I spent a good long time trying to see it working on a short playlist, and I just couldn't. As described, it's supposed to know that it's "shown" you the track even if you skipped it. So, logically, pressing unshuffle/reshuffle on a playlist with no duplicates should leave you at the same position in the playlist. I'm away from my empeg at the moment, but I remember it not working every time I tried to see it working.
