> Which is not dependence, but rather independence

Alright, well, good enough for me. Dependency tracking implies independency tracking. If that's what this is about I think the term is far more clear.

> where the order matters

I think you misunderstand the example. The article states:

> Like before, *the order doesn’t matter:* the client could begin a connection before the server starts accepting (the OS will buffer the client request in the meantime), or the server could start accepting first and wait for a bit before seeing an incoming connection.

The one thing that must happen is that the server is running while the request is open. The server task must start and remain unfinished while the client task runs if the client task is to finish.
