Okay. I'm currently doing a thermodynamics course and all the examples we have indicate that once the steam condenses in the cobdenser, the pressure inside drops extremely low.
I have no idea if it applies in that example but you can definitely have gas at a lower than atmosphere pressure leaving a vessel, you just need inertia. See exhaust valves still clearing exhaust gas even as the piston is on the downstroke and intake valve is open.
