clearly, the turner is confident in what he's doing..
You say confident, I say either ignorant of the potential dangers or complacent.
Use a spindle steadyWhile the spindle in the video is only about 8" long (guesstimate) it's also turning at a very high rate (unknown RPM) but IMO too fast due to the fact that it heats to the smoking point in about 1-2 seconds.
The longer the bore needed, the longer the bit, the more heat generated, the more potential for twisting and so on.

very basic principles for long hole boring, without any mention of technique, safety or commentary of any kind it's entirely up to use to exercise common sense.

Twice you've mentioned a three jaw chuck. I can't recall ever seeing a 3 jaw chuck in a woodturning catalog, although I've heard mention of them in metal turning situations.
Three jaw chuck is mentioned by the person who posted it in the description section of the video.
As I mentioned earlier this is a somewhat specialized procedure (long hole boring) so much so that Axminster sells a "system" for just this purpose.
