If B then A is the same as if X then Y is the same as if A then B. They are saying it's the same as the OP. Changing the letters around doesn't change the meaning since the letters are just placeholders.
Now if you said If A then B AND If B then A as one it wouldn't be the same because A and B would have to keep the same meaning.
They're simply stating the parameters where they perceive it to no longer be an easy convenient task. We'd need to argue that line to be sure.
