I think the concept of the scneario is that the Americans have to counterattack if they lose a building which is just about guaranteed instead of just concentrating all FP in one location...it's a 5 turn attack Counterattack game.A poorly written VC, however, I do agree that you need to have 3 SE in both, as others have stipulated. It would have been better to make it a positive type condition, i.e., the Americans win if they have >= 3 SE in both J4 and E5. Eliminates the entire and/or language.
OR the VC are just Jacked.
