If the blade is out of alignment to the table such that the rear is canted to the right, a crosscut will indeed be be square, (cove analogy works here), although the offcut won't be square. But if canted to the left, unless the work piece is pushed all the way past the back of the blade, which few of us actually do with crosscuts, the result will be out of square if the work piece is wider than the blade, as the back of the board will have been cut by both front and back of blade, whereas the front will have only been cut once.
