When you add a PIU terminal to a zone's air inlet node, the PIU secondary air inlet will automatically be connected to the zone's exhaust node. Whether you do this graphically in the OpenStudio Application, or programmatically through the API, it comes down to a call to the addToNode method which has the smarts to make this happen.
The "Induced Air Outlet Port List" displayed for the plenum is a crack in the Matrix. That property really should be hidden because connecting to the plenum in this way is not officially supported by the OpenStudio API.
