You described it perfectly. Honestly, while it is a very complex system, it does sound reliable overall. Just have to make sure that all those screws stay tight! You're right, there are multiple failure points which could risk the watch coming loose since there are so many screws. They probably use Loctite on the screws for added safety. I do like how the cap is removable, in case I scratch one. Maybe I can just replace the cap? Chopard might not sell caps though, they probably will force me to buy an entire link and a "8" shaped pin.
