Sorry, but another brake pedal question

Yeah IDK how it can find it's way back in. But if there is a booster on it, well there the pushrod is guided. However if it misses seating properly in the control valve, then a hard stop can break it, and then IDK what would happen.
I had a neighbor once with an old Ford Galaxie, that when he touched the brakes they came on full bore, slamming you forward hard. I traced it to a broken control valve.
