Thanks - that's extremely helpful. After reading your response, finding a good picture of the inside of the adapter and watching the video again, it looks like instead of the "normal" situation where barrel nut threads are torqued onto the receiver threads, the barrel nut torques on the adapter threads which then torque on the receiver threads. A mechanical engineer might take issue with how I said that but it looks like a pretty solid system. The downside I see is adding an additional part that could add variability to the alignment of the bore with the receiver - primarily the need for the adapter to be machined straight.
