It will result in taking the correct path becuase it forces the liar to tell the truth and the one telling the truth to tell you the truth.

You were real close. Yes you'd ask either of the guys "Which way would the other guy tell me to go", and you'd go the opposite direction.
Lets say the way you want to go is to the right. Well you ask the guy who always lies that question. Now the guy who tells you the the truth would say go right, but since this guy always lies, he'll say "The other guy would tell you to go to the left"
Other way around, if it's the guy who always tells the truth, well he knows the other guy would say go left because he'd lie to you. So he's honest and says "The other guy would say go to the left".
So you just go the opposite way.
