Because your pull command really means "merge in the topic branch from
peer_repo, and while you're at it, store it in my local tracking branch
topic". Remember that pull is really a fetch+merge. But the fetch is
actually doing _two_ things: putting the fetched branch into FETCH_HEAD,
and putting it in into refs/heads/topic. The latter fails (because of a
non-fastforward), but pull actually uses the FETCH_HEAD results to
do the merge.

Yes, this seems overly complex for what you're doing, but the reason for
FETCH_HEAD is to support pulls when you _don't_ have a tracking branch
at all (i.e., 'git pull ../peer_repo topic').
