Fetching from peer's public repo

My fetch from a peer's public repo seems to be failing:

% git --bare fetch git://source/public/project topic:topic
remote: Generating pack...
remote: Done counting 48 objects.
remote: Result has 34 objects.
remote: Deltifying 34 objects.
remote:  100% (34/34) done
remote: Total 34, written 34 (delta 22), reused 24 (delta 12)
Unpacking 34 objects
 100% (34/34) done
* refs/heads/topic: not updating to non-fast forward branch 'topic' of git://source/public/project
  old...new: 1c332f5...f3b18ff

I assume that is because his public repo does not contain changes I have pushed into my public repo. So, I asked him to pull from my public repo into his. He did, and said that git blathered that there were 12 changed files, etc.

I then tried the fetch again and it failed in the same way. If I look at the log output for the "old...new: 1c332f5...f3b18ff" line above, I see the changes that he has that I want to get, but apparently cannot (I tried to pull from my public to my private and it said "Already up-to-date."):

% git log 1c332f5..f3b18ff [... output looks reasonable ...]

Any ideas on how I can resolve this?

Also, what is the difference between:

% git log 1c332f5..f3b18ff

and

% git log 1c332f5...f3b18ff

with the latter having three dots instead of two? It seems to show much more output, but I don't know what the intent is.
