Huh? The same doesn't happen with vertical stretching. The direction of the graph correlates with whether the positivity/negativity of A in Af(x).

In vertical stretching, as A decreases the graph is pulled downward. Even as A goes negative, the graph continues to go downward. The opposite is true when positive of course.

This is different from horizontal stretching. As A in f(Ax) decreases, the graph widens away from the Y-axis (assuming the graph is symetrical along the Y axis), but once it hits zero, it stops widening away from the Y-axis and begins to shrink toward the Y-axis

This is impossible since, like Osc89 said, a vertical stretch is just a horizontal compression.

...Define vertical stretching?

@bolded, what you're describing sounds like shifting...
