It depends on your seating position, clothing and saddle. If you are wearing bike shorts and on a narrow racing saddle, the stuff rides high and central. You may have to do some adjusting and discrete tugging from time to time to keep it in place. The central member may be pointing straight ahead or tucked off to one side.
If you are wearing loose clothes and sitting more upright on a cruiser or Dutch style commuter, there might be a bit more draping to one side or other (or a little of both) but you don't want any crushing between thigh and saddle nose, so you still want the stuff to ride a bit high.

I find it all stays in place as long as I stay seated, but if I stand on the pedals for a bit, I may have to reach down and grab the stuff through my pants and pull it all up a bit when I sit, so it's back where it should be. I try to be unnoticed when i do it, but you can't always.

I do find I point the saddle a tiny bit to one side, but that is more to make my butt comfortable
