The defaultremote is a different system. The git remote have two URLS:
one for fetching and another for pushing.  When the setting is enabled
git-review -s change the push URL to point to Gerrit while the fetch one
is left untouched (ie: kept anonymous).

Example using GitHub to fetch but push to Gerrit:


$ git clone https://github.com/wikimedia/cdb
Cloning into 'cdb'...
$ git-review -s
Adding a git push url to 'origin' that maps to:
             ^^^^^^^^
        ssh://has...@gerrit.wikimedia.org:29418/cdb.git
$ git remote -v
origin  https://github.com/wikimedia/cdb (fetch)
origin  ssh://has...@gerrit.wikimedia.org:29418/cdb.git (push)
$


We fetch from GitHub:

$ git fetch --verbose
From https://github.com/wikimedia/cdb
 = [up to date]      master     -> origin/master

And push to Gerrit:

$ git push --verbose --dry-run
Pushing to ssh://has...@gerrit.wikimedia.org:29418/cdb.git
To ssh://has...@gerrit.wikimedia.org:29418/cdb.git
 = [up to date]      master -> master
Everything up-to-date


Profit \O/

We can still tune it a bit when it makes senses. But yeah with
Differential that will be superseed even if phasing out Gerrit is more a
few quarters than a few months :-(
