Yes, both lines represent the careers of Bryan Singer and Ronald D. Moore. Both lines also represent little to no productivity between the two of them in either Science Fiction cinema or Science Fiction television. Projects are announced supposedly coming from one or the other, and none of the projects arrive at completion.
I think a number of things are going on here as the causes of this lack of productivity:
1. Bryan Singer and Ronald D. Moore are vastly over rated as "supposed maestros" of Science Fiction media. Quite frankly, the two of them aren't very good at all at producing or directing anything in the genre.
2. Bryan Singer and Ronald D. Moore have had serious mis-steps in their handling of Science Fiction and Fantasy. Bryan Singer's serious mis-step was of course "Superman Returns" in 2006, which I believe led to Hollywood having a permanent "chilly reception" for Bryan Singer in any of his future desires to tackle Science Fiction and Fantasy. Ronald D. Moore's serious mis-step of course, was his handling of a project called "Battlestar Galactica" and its sequel series after that, "Caprica." You can't produce and write a television series which was really "Retaliatory First-Aid" on the "Star Trek: Voyager" television series and expect people to accept it as "Battlestar Galactica." The public didn't accept it and the rest is abysmal history. I also believe that Hollywood has had a similar "chilly reception" for Ronald D. Moore towards any of his future projects.
3. Since Bryan Singer and Ronald D. Moore both have an aversion towards producing and directing original material of their own invention, there are only so many Hollywood projects left that can be re-made in the Science Fiction / Fantasy category that any "Powers That Be" would be willing to give to either one of them.
Both lines above will no doubt continue running parallel with one another.
