I'm guessing Spencer remember she saw something about Byron in Ali's diary the night she found out Mona was "A". and "A" found out and got the same exact book and the liars found it, but it was empty except what "A" wrote, making the liars talk to Mona because she is the only one who read the whole thing.

That's why I think the books are the same.
