MAYBE I'm (yet) again WRONG
in my thinking???
The orientation of the plug is not supposed to make a difference in which post of the plug makes contact first or last. The ground post is slightly longer than the other two posts and if the plug is pushed/pulled straight in/out will be the last to lose contact. The internal design of the outlet also favors the ground post being first/last to lose contact. Mechanically a great deal of force would need to be used to disconnect the ground post while one or both of the other two were still connected. Probably resulting in the outlet or plug being damaged.
On the other hand an old deformed plug or broken outlet will defeat the safest designs man can come up with.
Yes, I agree, with the ground post orientated down, the ground post is even more likely to be the first/last contact made
