It's probably part of it but cutting away all the breaths and making the video as dense as possible reminds me of TV ads. You want to pack as much as much as possible in a short timeframe and sound super dynamic and not give the audience the opportunity to think about what they're watching. Trim all the fat. It looks like an infomercial almost.
Bingo, yes! You put the words to it... This YouTube style is exactly like those irritating ShamWow and OxiClean commercials that feature pitchmen filling every millisecond with their voice, without any break in the dialog. But instead of 30 seconds of it, they go on like that for 10 minutes. I tried to watch that video and couldn't take it for more than about 30 seconds. Totally exhausting.
BUT WAIT, THERE'S MORE!
