Thanks, now I think I have a clear picture. I think it's worth to add some more info to tutorial.txt about difference between fetch and pull. I don't believe I'm the only confused user ;-)

I was confused by the "merge" terminology, if I fetch to an empty branch the concept of copy is easy to be understood, but if I fetch to a branch that contains data then it's somehow more difficult to think about fetching without thinking of "merge the remote branch into local".
But now I think I understood it ;-)
