I think he thought you were referring to Lincoln being in each episode, not every title card.

But that has more to do with the fact that Lincoln does not appear, no matter who the protagonist is. By the way, I do not know much about Harvey Beaks, but this trope "A Day in the Limelight" is even more explicit in Star Vs. the Forces of Evil, where in certain episodes the protagonists of the episodes are people who did not interact much with the protagonist (one of them had not been presented before to win the own episode).
