Actually no because the output (reward or penalty) is not selective on your rationale. You can be bullish or bearish. The the input and the output are both allowed, just working at asymmetrical speeds (slower for bearish).

Wouldn't overall cause a "sustentation effect" similar to the asymmetrical speed in the airflow in the wings of a plane?

I'm not convinced myself of this, but the idea made me curious and maybe worth of experimenting with in a limited context?
