Fail. The point is to allow the plant to have as little side branching as possible, since most of it is popcorn. You are re-directing the energy into 4 main branches, which will the the top two you cut between seen in his picture, and the 2 below it, or even the two below that. You then wait for the plant to recover from the cut, a couple of days, and trim off all branches off the main stem, below the top ones you want. If you tie those four into 4 different directions, just slightsly to pull them apart, you get great light penetration.
The maintenance is the most important part. I lay on my stomach every night and keep cutting away the side branching coming off my desired 4 main branches, until they start getting to my desired height prior to flowering.
This gives me 4 heavy branches, that can hold themselves up, with 4 big colas, and a great amount of UPPER side branching that produces big nugs. Since you seperated them, there is lots of room for them to fill in, and you get a banging garden.
With this system, depending on the strain, I pull .9 to 1.1 grams per watt. It is a sealed room with co2, hydro (house and garden nutes), and in an ebb and grow.
It's a lot of work......but ever seen 6 lbs of fat frosty nugs, and 3 cases of fine trim in mason jars, and multiple gallon ziplocks of popcorn for making BHO? I don't include any of that stuff in my calculations either.
Do the cut.......I promise it's the way to go.

His sticky is all you need to know.....that's how I learned, and tha's how I teach when I consult MMJ patients in my State.
