As acknowledged pulling an ace on TTOP. Pulling a fifth starter not so much. Very well the difference between an ace and a three starter and a fifth starter seems to be the ability to maintain stuff deeper in games. That much the numbers does tell us.

And because the evidence shows it to be so different on a pitcher by pitcher basis, that alone is evidence that it's more fatigue than TTOP. TTOP is a BATTER thing... it's a benefit the batter supposedly gets by seeing a pitcher multiple times on the same day and thus the BATTER is more effective. If there is such a benefit, then it shouldn't matter who the pitcher is... because it's a batter thing.
Fatigue, on the other hand, is a PITCHER thing... it is a change in his effectiveness based on the changes he endures as his body tires.
As I've said before, there is probably something to the idea that batters gain some advantage the more they see a pitcher overall and the more they see him in a given day.... but most of the decline in effectiveness over the course of a game is almost certainly due to pitcher fatigue and not this "benefit."
