One point that I didn't see mentioned was the inability for the wedge to work as well. When the backcut is horizontal, the pressure from the underside of the wedge is directed downward into the stump, which can be compressed when dealing with decaying sapwood to begin with.

The higher the angle of the backcut, the more the wedge is forcing forward (as noted in multiple replies), but maybe more importantly, the wood below the wedge being pushed downward and backward is more likely to blow out under the load.

Plus 1 regarding the harder to line up sloping cut to allow for a perfect hinge.
