I guess its author thought the "A" and "B" in the example have exactly the same meaning as "A" and "B" in "ABA", but that's not the case. In the example, the real problem is indeed that B has been deleted; in general, ABA can cause all kinds of problems, even if B doesn't get deleted. undo Tag: Undo
