The management thinking from your example seemed very natural and not so surprising after all. They just needed someone with a "just in case" mindset, similar to the tailor from one of my favorite scenes/movies "The Hudsucker Proxy" - "The Double Stitch" [0]. I even sometimes act like that character. For example, when the boss says we will drop a feature, I don’t fully kill it, instead, I temporarily disable it because the chances of it coming back are not zero.
