It makes some sense if you consider it a representation of the way you'd speak/read the sentence. If you read that sentence out loud, regardless of where you put the question mark you'll have to intone the quote as if the quote was a question, due to its context. So it functions "better" as a reading hint. (Though I'd also prefer to have the punctuation outside the quote.)
