It might depend on what kind of riding you do. If you are just cruising in the drops a lot, then you might rotate your hands to the outside, thus necessitating the "advanced parktool method". For me though, I don't rotate my hands to the outside with any force if I am just cruising, but I definitely do rotate my hands to the inside when I am pulling on the bars during a sprint or hard acceleration from the drops.
I'll trust my experimentation over what some website says.
