In general making a drastic change to a question without the OP's collaboration is not appropriate, and it's not in this case. You may think that's the root of their problem, but you may be wrong and/or they may disagree. Given the amount of comment argument over there I'm not sure you can claim that everyone else is in agreement with you on this, either. So let it lay.
As for you asking it separately - why, is it a problem you have? We find that when people ask questions where they don't have standing - in other words, the question is not a question they really have - those questions and answers end up sucking. As it's hypothetical no one can get good clarification on it, answers tend to be cursory, etc. It's "legal" to do but I would never do it personally and find it gauche.
