How to U turn an orchid

[PuiPuiMolcar]

I cant link youtube here but there's a Video about U turning orchids that tend to spill out of the pot by Bumblebee's Orchids.

I thought this was interesting, I've always been curious how cultivator grow their orchids more bushier and compact when all of my supposed mini catts will invade as much space as they want. I have tried giving them overhead light, leaning them against a surface, tying them etc.
Zygos and some oncidium frustrate me the most because they grow vertically.
