There should already have been a remote.origin.fetch that looked like:
$ git config remote.origin.fetch
+refs/heads/*:refs/remotes/origin/*
which is a superset of what you added. If you run the git config command I did above, what do you see? If you have a wildcard line like the one above (which is added during the initial clone), then the config you added would have done nothing.
Are you absolutely sure that the branch was pushed to the remote side in the first place? How did you push it?

There isn't really a shortcut for the two-level thing you're trying to do. But consider rearranging your topology to always pull to the local repo, and then push changes up to your backup/collaboration server.
Something like:
$ git clone http://github.com/whatever/project.git
$ cd project
$ git remote add myserver myserver:/path/to/backup repo
and then your workflow is:
: hmm, I feel like working on project. what happened upstream?
$ git pull ;# or git fetch origin; gitk origin... ; git merge origin
$ hack hack hack
: ok, now I have some work to show to my collaborator
$ git push myserver
or possibly:
: ok, now what has my collaborator been up to
$ git fetch myserver
$ gitk myserver/topic
: I like it, let's merge
$ git merge myserver/topic
: Now push back my merge
$ git push myserver
You might also find it convenient to swap which remote is "origin" (since it is the default for "git push" without arguments). That is, you primarily consider your local repo to be a clone of what's on "myserver", but you occasionally fetch and merge changes from upstream, like:
: ok, what has my collaborator been working on?
$ git pull
: and what has upstream been up to?
$ git fetch upstream
: oh, neat stuff. let's merge it
$ git merge upstream
: and then let's publish it so our collaborator will also work on top
: of it
$ git push ;# implicitly to origin
How you want to set it up really depends on which mental model represents your workflow best.
