The only reason I can see FFG enforcing a correct model rule is yes the scalcon is unmistakably a yt1300 but say you are playing rebels and your opponent is scum. It might get a little confusing if you both are using the same model for 2 different ships. At that point on the board they would look identical aside from the baseplate if the nose is off. Rebel and resistance would have the same problem. Colored baseplates and number chits would fix this though.
As for only buying one faction, I figured that was a lie when they said it. It might be true for casual play or looking at a timeline through the lens of infinity but as far as playing competitively it’s going to be largely false.
