The examples, as I would expect of the phrase in context, have a dismissive tone that reframes the question as an assertion. It's usually a pretty innocent faux pas, and can feel natural to say, so it can be hard to catch oneself in it, but I try not to say things like "simply X" or "just X" when explaining or asking things, in an effort to keep a neutral tone. Is that the point being made here? I don't know.
