Any common sense logic on how the pins/clips face.

We have a saying in our industry, "Complacency Kills". Whatever kind of pin/clip/lock arrangement you have you should look at them every time you prepare to get behind the wheel. You may think your locks will stop any chance of shenanigans, but how much are you willing to bet on it? It only takes a second to make sure the pins are in place and the hitch is latched.
