Much better video, I'm sure you didn't mean to post that non-discernible footage the first time around.
What IS abundantly clear from your video is that the steel foot on the door sill is flexing downward into the plastic bumper. So while it may be in contact with the tire carrier frame & door edge, it's not 100% structurally supporting the door.
The factory mating tab and slot you showed inside the door frame is providing more structural integrity than that foot is. You demonstrated that it corrects the weighted-down door into the right position, so that the latch will lock shut.
It will probably be fine in the end for most users, but from my perspective, the JWO design features a lot of cosmetic engineering.
