I classify this type of fingering as
"crossing fingering". It is useful for harnessing wild changes in
left-hand's position.
Suppose that you want to repeat the bar
provided in the
tablature
for unlimited times. Also suppose that you have started on B-string, fret 3. As you see in the tablature
and video, if you avoid
using "cross fingerings", the pattern will crawl the fretboard until it
finds a suitable fingering somewhere between 12th and 17th frets. But if
you adopt "crossing fingerings", the position change will immediately
stop between 5th and 8th frets.
The video includes both ascending and
descending examples for "crossing fingerings".
