You want the walls flat, so the tapered long edge on the drywall can allow you to get an indentation unless you're careful, and what you use to embed the Kerdi across that joint is not long enough, or you misjudge and get an edge in the depression. FWIW, the paper on drywall is directional, and it really is designed to be installed horizontally, not vertically, so it attains its maximum strength. Make sure to use the specified screws at the specified spacing.
