You can see the de-spin at 0:57 and at 3:47, where it really looks like a bolo is flying away, but I can't be certain. It's only a few frames and it's not possible to slow-mo Youtube videos (or frame advance). YouTube frame advance. Pause video. Press period key to advance and comma key to back up one frame at a time.
The video is great - even though there is no sound in space, the vibrations of the craft are picked up by the cameras.
