So it looks like the rubber seal is designed to mate (with high enough vacuum) to the small exit hole in the center?
Yes, that is the way I see it as well. If the suction or negative pressure being applied by the turbo becomes to great, it will pull the rubber diaphragm down overcoming the small spring and close off or regulate the flow leaving the puck.
The top of intake has a long narrow upper chamber with three ports cast in it that allows the the flow to go up and through this chamber and then into the puck.
The flow then goes through a spiral in the puck much like a spiral seashell or watch spring before it finally enters the center of the puck where the flow must turn up to enter the outlet pipe going to the turbo inlet pipe. The center of the spiral right below where the flow must turn up also has a small port that will allow oil to drain back into a small cavity in the intake that has a single drain hole in the corner that has the "J" tube or trap connected to it. I believe this "J" trap acts much like your sink trap to prevent any flow into the puck but only allow oil to drain out as it accumulates.
I strongly believe that having a pipe that forces the flow to go up and over an incline that is higher the the top of the puck will help prevent a lot of the oil from ever leaving the puck.
That is one of the reasons I installed a metal pipe between the puck and the Provent on my Jeep. I now get very little liquid trapped in the Provent anymore.
picture shows metal pipe before insulation. Note the rise leaving the puck.
