I think that's a bit too direct an interpretation of his words.

Take the Phantom Lord arc for example. While it's true that Lucy and her relation with her father were the driving force behind the conflict, she didn't have all that much screentime really. And her actions had very little impact on the story overall in that arc. It was more about what was done to Lucy than what Lucy did. In other arcs she had more screentime and a more active role.

Same with Laxus and the fighting festival. Until the finale, we only saw him talking from time to time and during the majority of it he was off-screen. But he was undeniably the driving force behind the arc.

Thus I think we can't just take this "focus on character X" quite so literally and equate it directly with screentime and the number of scenes X is involved in.
