I can also see the value for a large organization in culturally enforcing interchangeability and replaceability of workers.

I always considered this bit of culture (and felt the message this way from coworkers) to be even more focused on on well-being of the would-be hero. It always comes alongside messages about how to deal with burnout or achieve a work-life balance that works for you. That's always been my preferred perspective on it, anyway.

Still, I'm with you in pushing back against the interpretation you quoted, which is at best a weak (and at worst toxically macho) understanding of real motivation behind this anti-"hero" sentiment. It's mildly absurd to say there's a culture of holding back hard workers in order to lighten the expectations for everyone else. Anyone who works "twice as hard as expected of them", broadly speaking, just gets recognized/rewarded/promoted until expectations and output match.
