He's saying that in the context of tracking a remote branch. He's saying
that if I'm pulling from your repo and I haven't made any changes, then
it's pretty rude of me to add random empty merges which only signify
when I happened to run the "pull" command. What I really want it to just
collect your changes and add them to my repo, using fast-forward merges
to move my branch to the latest commits.

In particular, I don't believe he is saying anything about merging
across release/master/feature branches. In fact, I've seen many people
advocate "git merge --no-ff" when merging important branches together.
