The bike is tilted back underneath a rider going uphill.

I believe what we are talking about is ease. It is easier to hold high resistance on a hill than it is the flat. On a climb, gravity limits the effect of momentum on your ability to ride with high resistance. On the flats, it is much harder to limit those same effects.

Gravity hasn't changed and still points down. As a result, to keep your weight over the cranks you need to shift forward. Eventually as the grades pick up you reach a limit where you can't do this further, and you end up with your weight back behind the cranks, and pulling on the bars to hold yourself down. Note that it's the bike that rotates underneath the rider. The rider ideally stays above the cranks. When you rotate the bike underneath the rider, the effect is that the saddle is moved back and down, and tilted up. This makes for a different riding position. When you reach the practical limit of your hip/groin angle, your weight starts shifting back as you can't go too far forward on the saddle without losing too much leg extension. When this happens you pull on the bars to pedal to hold yourself down. When grades get even steeper, maybe around 14-15%, you have to shift your weight forward and smooth out your pedal stroke to avoid lifting the front wheel.
