That's not how the parent is interpreting that statement; their interpretation of, > If p and q share approximately half of their upper bits That, of the upper bits, are approximately half are the same? Since the combinations of two corresponding bits in p & q are 00, 01, 10, and 11, and, if they're chosen uniformly, one would expect about half to be the same. I suspect that your interpretation is what the article wants to say, but I think that the parent's interpretation is reasonable given how it was written.
