Ari, I think that's because Glitch just tells the directions, but not how far you went into a particular one. So when it says "you go west and then north" it could be you went one meter west, then one meter north - but also you went three meters in the west direction because for that long there were no other paths, then you turn north and there you have to walk straight ahead for seven meters until you reach a forking path.
