frownie "cheating" trick (another question about border case rules)

I’m sorry, I have board game background that translates in “rules breaking” habit - learning process when I play them out in my mind.

When I have received so many frownies that I hit the bottom (flow 1), last one or more will hit me with less then 3 flow. Every returned frownie will restore 3 flow regardless hit I took from it.

Do I interpret rules correctly?

You only get back flow that you lost.
