Executive producer (Donald's role) is not the producer. The producer runs the show. Executive producers sign their name to a project to give it visibility. An executive producer can give advice and guidance but doesn't actually have to do anything.
Yes and no. On a TV series, a show runner, who is actually in charge of day to day operations, is credited as an executive producer. However, it does stand that not all executive producers are showrunners.
As an example, JJ Abrams and Jonathan Nolan were both executive producers for
Westworld, but Abrams basically did nothing while Nolan ran the show.
