>If you unfold a square, you don't get two squares.
yes, you do. Two squares will fold together into the space of one square, and the same with 2 A4 sheets of paper, or two 8½x11 sheets of paper, two of them will fold together to make one of them.
I'm not exactly sure what you're trying to say, or what would refute what I said.
You said: "If you unfold a square, you don't get two squares."
In the context of this discussion, it is reasonable to assume that any "square" available to be unfolded is something approximately like the folding phone, consisting of two layers joined by a hinge. When you unfold that, you go from having a square to having a rectangle equivalent to two adjacent squares, and usable as two adjacent squares.
I see. I agree (obviously, it's a fact), but in the context of this discussion about aspect ratios and why the golden ratio would be relevant to this situation, it is reasonable to assume that the point here is that a full-screen, unfolded image would scale exactly to a half-screen/folded image with no change in aspect ratio.
