No, the point is that if you're not asleep within 20 minutes you should wind down more outside of bed and try again. it helps me to reinforce the "no phone/reading/whatever" in bed rules, and means I don't lie awake for hours in bed - I get up and read in the living room for an hour and try again.

I've tried this method. It involves me sitting somewhere else until 6am not being able to sleep instead of my bed.
