Question on a growing technique and or pruning style

I've seen these plants with a bunch of stems coming from the same place near the bottom. How do you achieve this? I asked in this guys thread, but maybe I'll get a answer here.

Yup, LST or check out manifold/main-lining your plants. That is if you enjoy the more uniform look and weren’t necessarily looking to fill out your canopy.

No matter how much topping you do, the stems won't resemble that until you switch to flowering. I saw pictures like this while I was still early in the veg stage and I was topping on a regular basis. I was thinking "why the hell isn't my plant looking like theirs?" then I switched to 12/12 and the stems started to stretch... then I started to see that my plant looked like theirs...

I've main lined a plant before, but that was the basic nebula way; two stems into 4 then 8. But its distinct. The picture in EL Connoisseur's post is like a bajillion stems all from one spot. Unless its ridiculously tight node spacing with topping. I've seen a few of these plants like this.

Def not mainlined.. looks to
Me like he topped and tied down and kept topping and tying down! While opening up
