If it has a name, I don't know it; but I'm guessing that it is just a flatmuslindrop with nylon webbing with d-rings on the back, with cables running down to a stout bottom pipe. It looks like a great option for theatres with no fly space.
Somebody want to take a first at bat on difference between Austrian and Braille? Correct spelling for braille or brail? Where does contour fit? And why aren't they called west coast?
It appears to me that in the video, there are two separate soft goods. A Painted scrim DS, and then another curtain, maybe a fullstage black or some other masking drape, and they both roll rather than fly, probably due to lack of height for full working flys. It also appears that it could be that there is a projection, and the border of the projection makes it appear as if there is some sort 2nd drape.
Well to my eye's they have a Main Curtain rigged to travel
Then behind that they have an Olio or Drop made from either Muslin or Canvas, with Brail rigging, rigged to a bottom pipe.
And I can do this without looking ( I hope or my stage carp would be disappointed )

Austrian refers to the amount of fullness in your curtain, which from what our designers have said in past differs from curtain to curtain and theatre to theatre depending on designer and curtain company. Can be minorly adjusted with lift lines but this tends to distort the fullness
Brail is a rigging that pulls your curtain up from multiple points from the bottom up
Contour is like Brail except you pull the points different amounts and can stylize how the curtain goes out from those points... How you get the clamshell effect
West Coasting is a method of gathering goods for quick transfer from pipe to pipe, ( can also be used for storage but not best practice for long term.)
I've helped rig all of them in my career so I hope I got that right
Definitions vary, and I'm sure there are long threads about it. Here we tend to use "west coasting" to mean gathering a drop similarl to how you've described, then using a few ties to tie the whole bunch to the pipe for storage. Also called a "sail tie."
Only a guess: in a film studio you don't have a fly gallery but might be able to fly in a pipe to gather a drop and quickly store it out of the way on the pipe.
