Imagine instead that you extend a piston through the blue portal. Eventually it comes back and hits itself from behind. The piston can't keep extending into the portal because there is no "inside" of the portal - "inside" the blue portal is "outside" the orange portal, and vice versa. At this point one of three things could happen. If the piston is weak it should crumple, the same as if it were pushing against a solid wall. If the piston is rigid and the portals are super heavy, then the piston will just stop expanding (since it can't lengthen any more without the portals moving farther apart). But the orange portal is clearly "pushing" the piston out of it to the right, so Newton's "equal and opposite" law of motion means the piston is pushing the orange portal to the left - "kind of like what happen
