Riddle of the Two Guards - More Than One Answer?

This s the riddle:

You stand at a fork in the road. Next to each of the two forks, there stands a guard. You know the following things:

1. One path leads to Paradise, the other to Death. From where you stand, you cannot distinguish between the two paths. Worse, once you start down a path, you cannot turn back.

2. One of the two guards always tells the truth. The other guard always lies. Unfortunately, it is impossible for you to distinguish between the two guards.

You have permission to ask one guard one question to ascertain which path leads to Paradise. Remember that you do not know which guard you're asking -- the truth-teller or the liar -- and that this single question determines whether you live or die.

The question is: What one question asked of one guard guarantees that you are led onto the path to Paradise, regardless of which guard you happen to ask?

The answer: Ask one guard what the other guard tell me to do (and then take the other path).

Would this convoluted answer also work? "If I ask you if I should go left to get to Paradise, would you answer 'yes'?" Assuming that left is the way to Paradise, the honest person will say "Yes." The liar will think about it. The honest answer would be that he would answer with a lie and thus say "No." But he has to lie, so he will also answer "Yes." So you should go left. (Conversely, you could get two "No" answers if the road went to Death.)

I think this works, but I may be missing something logically.
