You're assuming he knew where he was. There's a good book called Sahara Unveiled that has several stories in it about people getting lost in the Sahara and dying of thirst. In many cases they were only a mile or two from a place where they could have been saved. The problem is the roads aren't good and are often covered by sand, so people get disoriented and don't know where they are or where they are trying to go. Plus if you leave the shade during the day you will lose water even faster. Maybe this story is fake or staged, but many people have died of thirst in the Sahara even though they could've walked out.
