Momentum S-parameters Simulation quest.

I have a general question about what exactly the S-parameter simulation is doing in Momentum.

Say i have a layout that has 8 internal ports( for smt pads) and then 1 in and 1 out port, for a total of 10 ports.  I am concerned that when momentum runs this simulation, it stimulates one port while all the others are terminated in 50 ohm loads.  However in a real circuit, that would not be accurate as your internal ports( pads) would not be terminated this way. Really only the truly source and load ports should be terminated.

Is my interpretation of this correct?
