I think it’s how it works everywhere. People see who’s good at their job and promote them to manager; an entirely different job though people often think it needs the same skill set.
Isn't this like a recipe for the Peter Principle?
"The Peter principle is a concept in management developed by Laurence J. Peter which observes that people in a hierarchy tend to rise to "a level of respective incompetence": employees are promoted based on their success in previous jobs until they reach a level at which they are no longer competent, as skills in one job do not necessarily translate to another"However, none of this has much to do with what I said: isn't promoting someone for things they would have to stop doing (as in TFA) a recipe for the Peter principle?
At some point, we have to understand articles and blog posts like the one we're discussing are mostly fluff; an ad for the person writing them. They are self-promotion, there's not much sense in trying to extract valuable lessons from them.

I thought of another analogy:
"You're an excellent marksman and a sniper, therefore we promote you to... general of the army!"
But, you could argue, maybe the sniper was already directing strategy, and that's why he got promoted? Nope, TFA is clear about this:
"To get to principal, you need to put yourself on the critical path. To be effective as a principal and go beyond it, you need to actively remove yourself from it"
