As far as I know, it's never been demo'd in a video. And yes, I use it frequently when I'm running a duet of characters (usually using a light system like World of Dungeons or my Remix of it) and I don't want to "make a call" for what the hero does --- it's really fun to be surprised. By default it's weighted towards "act heroically", "do the expected thing", and "demonstrate a strength", which is what you'd probably choose for the character anyway, so you can also mix it up there by rearranging the agenda table.
