When a monster moves, it moves the shortest distance possible to reach it's target, thats it. Otherwise the monster controller can FREELY decide which ever way it takes, play it how YOU want to.In your example you can face the monster which way you like.
A further thing to consider, for now everything is quite simple and it might be easy to say which way is ultimately better for who. But later it might easily get much more complicated and different options might both have pros and cons, that's why there isn't a specific rule for moving in the monsters or survivors favor.
