Slater to answer your question, I believe you are asking, if a club you hit is too upright for YOU, you will tend to pull hook since the heal of the club will hit the ground, (toe of club off ground), conversely a club too flat for you, will cause a push slice, since the toe will dig in, hit ground first, this has the effect of closing/opening the face. This is why custom fitting is SO IMPORTANT, it gives you the best chance at a pure hit, with little or no ground influence of the face angle at impact. Too really get a good visual of this, find an old dart from a dart gun, (you know kids toy, with the suction cup) now place that dart on the face of a club, sole the club correctly and note how the dart faces directly down line and at the correct angle angle, now lift the handle so the heal comes off the ground, (this simulates a flat lie, toe heavy), see how the dart now points right of target and higher trajectory, thats the same direction the ball will go, and the face is still square, you haven't changed it, then bring the handle down, heal heavy, toe in the air, dart now points left, and very shallow angle, same thing, you haven't changed closed/open angle, but you can clearly see, dependant on weather you are heal or toe heavy, these angles ARE dramatically changed. Hope this gives you a better understanding of loft and lie.
