That is my interpretation, yes. "Fully self-driving features" means the car is self-driving at least some of the time. So a fully autonomous mode that's only active on the highway in good weather counts, but not modes where the human still has to pay attention, or features that only support but do not actually enable full autonomy at least some of the time.

Even limited full-autonomy seems totally out of the reach of Tesla given what we know to date.
