heroku fork + heroku git:clone = New app works but empty repository

I have a Heroku Rails app called app1 which has source code, and works.
I wanted to create a new app inspired from it but different, with different code and URL so I ran:

$ heroku fork --from app1 --to app2
$ [...]
$ Fork complete. View it at https://app1.herokuapp.com/

I checked at that URL: The cloned app works correctly.
Now let's clone it to my local computer so that I can modify it:

$ heroku git:clone -a app2
Cloning into 'app2'...
warning: You appear to have cloned an empty repository.
Checking connectivity... done.
$ cd app2/
$ ls

PROBLEM: Nothing in this folder. The repository is empty!
How is this even possible? Is the app working without code?
Do I have the wrong command for creating a local copy of the code?

Jon's answer explains why the repository is empty.
Here is how to fix the "problem":

$ cat app1/.git/config

Take note of the value of url in the paragraph origin.
It will probably look like [email protected]:app1.git.
Then run:

$ cd app2
$ git pull [email protected]:app1.git
$ git push

This will retrieve the source code (ignore the Your branch is based on 'heroku/master', but the upstream is gone. message) and replace the cloned slug with one built from this very source code.

Yes, see the documentation that states that the Git repo will be empty.

The app is working because it has the same slug.

In general, I advise not to think of Heroku as a source code repo - but rather put that in another place (like GitHub, say).
