1) I've been doing something like that for years - roping a limb off itself.
2) The stub was too short/the saw was too close to the rope. An extra 3 or 4 inches wouldn't have hurt.
3) I'm interested in that quick release stopper knot. I would imagine it only releases under a light/medium load?

Its like the Belay Spool, but better.

Its not meant to be used with a POW.

Making the friction point up top means being able to transfer the load to the climber, freeing the groundie up to land the piece in a tight dropzone.

Also, it reduces the load on the top anchor point.
 
I would think that locking it off like that would increase the load as opposed to letting it run a bit, not a big deal in the video cut but it may be nice to have a ground person hold the rope at first then switch over control of the line.

I agree the stub was a bit small in the video.

When snubbing it off like that, there is a high shockload on a very small section of rope. This is worse for the rope than snubbing it off with a block, where there would be much more rope to share the load with more stretch.

I would just hold the tail, or have the groundie hold it, and let it run, either way.
