Yeah I'd always taken it that Decker's recommendation of "defensive posture" and Kirk's counter with a more cautious strategy was the indication of what would have happened to the Decker-prise.
It also - on my billion rewatches of that movie - always seems to be the reversal point of the narrative between Kirk and Decker. Kirk had endangered the ship with his lack of knowledge and patience during the torpedo incident; here was our old Kirk back finally, and contributing his skill for the first time since his return. Decker is smart, but this showed his inexperience "out there."
Of course, I read into things.
