Sure, and I think the comment he replied to means "the term competitive is ambiguous, let me clear it up: this is not talking about advancing your career."
I guess, to the degree that you would assume "competitive programming" could be interpreted as something specifically to advance your career, which I know I didn't, and I'm not sure how you could (but I could easily be missing a common different interpretation).
That is, I wouldn't assume "A Competitive Fisher's Handbook" would apply to my career as a bulk tuna fisherman, and I would find a comment that points out that there is nothing related between the two as as both obvious (colloquially), and overreaching (specifically) to the point I might feel the need to counter-correct as there very well might be links between them that could help in non-obvious ways. That competitive programming and interviews share more than superficial similarities might make me even more likely to do so.
