If that is the case, the game manual should be changed.
"You can use entirely your judgment (Strictly Follow Depth Chart)...or you can use your depth chart strictly until the 4th quarter, then tell the coach to try and win the game however he thinks is best (Depth Chart until 4th)."
Clearly, if I told the coach to only play Montanaro at PG, but he pulled him for the 4th, the substitution strategy was not based ENTIRELY on my own judgment. If I told you that I ate an entire apple pie, but you know that you ate a slice, you would call me a liar. Same thing applies here.
The developers should change the how the tactic is implemented (my preference) or change the guide book, because the status quo is misleading.
