Wait, did he get the wiring wrong?

I was under the impression that cables with power delivery used two pairs of power and ground (upto 20V iirc). https://images.anandtech.com/doci/11667/usbtypec-pins.png

Cables with power delivery have a single wire for power negotiation (CC) and a single pair of power/ground. The connector, on the other hand, has two CC pins (one of which is connected to the CC wire, and the other is not) and two pairs of power/ground. It also has a few other things - a pair of wires for weird low speed uses (SBU) and an additional pin for supplying power to the cable in case the cable itself has a chip in it.
