For the second case, if the HB were at the same level as the saddle, it would be pointed up.
That depends. I prefer Brooks saddles, and many have observed that most Brooks saddles are pointed up a bit, and that's the case for me. You usually see Italian style saddles* dead level, at least on bikes with experienced riders. And this is with the handlebar somewhat lower or higher than the saddle.
*Italian style saddles: my term for a plastic shell with a cover glued or stapled on, usually with padding between the shell and cover.
