Issues-Only Access Permissions GitHub

Question

I am trying to follow the Issues-Only Access Permissions help information at GitHub, but I fail to understand how the issues propagate from the Issues-Only repository to the private repository.

Can someone please clarify in more detail?

You can use commit messages to close issues across repositories.

For instance, if you have two repositories, tyst/project and tyst/project-issues (with the former hosting the private code), you could close issues in the latter by using commit messages (like fixes tyst/project-issues#14) so long as the person making the commit has write permissions to both repositories.
