No need for water. In my mind that time in the flame was NOT long enough.
Those cases were dirty/off colored looking around the neck already.
Not bustin your chops just the dude on the video.
Use a heat indicator fluid like tempilaq or use the Sharpie marker to make sure you got the heat up enough.
I have used both heat indicators back to back and the Sharpie is spot on with tempilaq and easier to see fade.
But yes in the video that is basically how you do it.
