He would ask one guy if you was the other guy which path you would tell me to take. The liar would tell you that the other guy would tell you to take a spefic path and you take that path. If the guy was the one telling the truth he will tell you the same path and you would take that path. 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.
