No, as far as I can see he connects +5V to the 3.3V pin, not to the 5V pin.
The 5V pin (VDD 5V) goes through the onboard 1117-3.3V regulator but the 3.3V pin he is using goes straight into the ESP chip. The chip will die because 5V on it's 3.3V pin is too much.

What in your description indicates that you "Destroy ESP8266"? One thing I see in your schematic, you are using 5V to power NodeMCU, form what I read in docs recommended power is 3V although there is a pin-out you seem to be using that can run this unit at 5Volts I would try to reconfigure to use 3V or USB power to test. Unless you have requirement to run this at 5V.

The value of the power supply is in the safe range:

From schematic PIN 15 is 5V VDD

From your Schematics it looks a bit that you don't Connect Ground of the NodeMCU. Is this an Error in your Schematics?

My block diagram is not 100% precise..the GND pin used is pin 7 from the "right" side.
I have to say that all the time the entire pcb was near (5-10 cm) a bunch of wires powered with 230V AC (@ 60Hz)
