The QR code video shows a ton of people going through the turnstiles quite fast. The one guy that didn't go through might have run out of credits, and needs to top-up.
So those two videos actually demonstrates that QR codes is actually more than fine. NFC might be faster and more convenient but the difference isn't huge.

The QR readers are certainly not “quite fast” and that’s nowhere near “a ton of people.” That QR gate wouldn’t stand up even on a weekend at a mid-range Japanese station.
