His point was that in matter/anti-matter reactors you need something (like dilithium) to regulate the flow of particles from one chamber to another. He simply filled in the gaps, but essentially credits the writers with forthright vision for coming up with basic fusion principles before scientists came up with it!
Yeah, you need a carburetor for an engine to work... big whoop. It doesn't take much to figure that if you have an engine, you need something to regulate the fuel. Yep, lots of forthright vision there.
