It has a bunch of benefits that are limited to blueprints and other similar designs. It is easily reproducible at a variety of sizes, clear, unambiguous and can be done with the tools available to a draftsman in their standard work. The sloppy lettering in the video fails on all of those counts. Unfortunately as more people become familiar with the look of the technique through old images and fonts, while fewer people are using it properly, you have people latching on to some of the quirks, but losing the value.
