Oil weight?

Ok I'm confused. I don't want to start a flame war about oil brand....but I'm confused about oil weight.

The shop that did my prebuy said to use 0W40 (they use Mobil 1 European blend). I see many people online using 0W40.

The owners manual lists the following viscosities for synthetic oil, "mostly higher than 50F":
10W40
15W40
15W50

For "mostly lower than 14F" they list:
10W40
10W30
5W30

So how would 0W40 be ok? I guess because it is warm now the oil will be thick enough?
