That is confusing SWP as per the video title, with VRS.
Whilst at that low level the symptoms are the same - you get the shudder and a rate of descent - a recovery with power isn't possible because there isn't enough available (hence the term settling with power).
How do you know there isn't enough power available here? Isn't it possible that the power he had couldn't stop his decent because he was in the vortex ring state?
