If we go by the original usage of the term, then yes, it's different skillsets between Ops and DevOps. You can't announce an Ops position with a DevOps title since the two are different by definition.

However, even if we go by your definition that it is the same thing, then the "Dev" part is completely redundant and we should just call it "Ops", since it's by definition the same thing and it doesn't warrant a new title, because it's the exact same thing. However I doubt that's what the case the original article is talking about.
