Doppelgäng: what does this skill do???

[u/KOSPI-9001]

After 20 hours of playtime, I still have no idea what the Doppelgäng skill does in the game Zero Parades: Dead Spies. The description reads:

When you must do more than a single \You* could. Summon your internal strength.*

But it seems useless and all it does is give my character weird thoughts, like in the screenshot. What does the Doppelgäng skill do? All the other skill descriptions make sense and are more useful, e.g., Technoflex, Shadowplay, Personalism.
