Without looking into the specific legislation, on the surface it looks like a reasonable interpretation.
All of the references from Uber state they are doing "self-driving".. which isn't IMHO Autonomous, as it is only Level 3. https://newsroom.uber.com/pittsburgh-self-driving-uber/
I'd expect Uber to obtain a license when they are ready to move towards driverless autonomous development, such as Level 4/5.
