As soon as it says "here or there" the writer is clearly trying to make it binary again. It isn't "here or there" but a function of probability between those two "places." It's an infinite number of possible "locations," but we narrow it down to a large number of decimal places because otherwise we wouldn't be able to make use of it at all. If things were as written here, you could do all quantum calculations with a straight up coin toss (although some might argue that can with an adequately tiny coin, but that still only gets at the most basic understanding of "spin" and only becomes an accurate analogy if the coin is flipped randomly in zero-g).

Our higher level concept of gravity (at least in the classical sense) has been known to break down to the point that it doesn't apply to quantum mechanics for quite a long time now. The writer should just google "quantum gravity" to discover what a complicated subject that becomes.
