I got the molle option, and it rides pretty low. Not much of a problem so far, and I usually prefer horizontal mounting myself.
One nice thing about the molle option, is there are two vertical straps each with a snap at the bottom, and one fixed horizontal strap. (Referencing the pouch standing up normally.)
I thread my belt through the two vertical straps, with one on each side of a belt loop, and then run them under the horizontal strap. It stays very secure that way, and when I'm in the restroom, it holds it securely enough that the weight of the pouch and its contents doesn't pull my belt out through the other loops.
Here's a quick pic, to show you how the straps are set up.
