Yes you have. In option #1, when --host is call you only return that one host and it's host variables, if any. (You said a single group.) You don't return any groups or group variables.
The dynamic inventory plugin API is a coarse-grained one that slurps in everything it can get from the inventory source. There are many reasons for that such as tasks that reference other host resources not targeted by the play.
