>I already understand how portals work
This too is ultimately a diversion, because the portal is just a hole through the wall. Any of these diagrams that are drawn with portals apart, could just be redrawn with them the same direction and then cancelled out to make a weird-shaped slanted mirrored room, where physics works exactly like the real world. Picrel shows exactly that sort of diagram, used as an extremely thorough explanation for the original question.
