I see where you are coming from. However, the feature is not the same thing as what it allows you to do.

There are:

 - *Automated Builds*, the feature: comes with the Docker Hub for people to use. It is one of the many features of the Docker Hub.
 - An *automated build*: a repo with provenance, automatically built by Docker Hub / what the feature allows you to create.
