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).
However, a pilot experiencing that scenario who mistakenly decides to employ the Vuichard technique because he thinks it is IVRS - will, as SLMFS says, crash and roll over.
Oh dear now we have the SWP agreement in. You are correct Crab re the title but surely this one is early stages of VRS? Downwind approach with flare sounds like the set up to me.
