I had the time to watch the video. He demonstrates (schematics and images) that a common anti-boneheaded design consideration Apple had adhered to in the past - spacing high-voltage traces away from very-low-voltage traces - disappeared in a more recent model (making it easy for 40+ volts to reach the CPU). One professional EE would absolutely notice this. So there's no 'maybe' here.
