This was how a read it too, but I don't think I articulated that to you well enough during our initial exchange.
And I regards to the climax being a bit of an anti climax for this chapter? I think I feel like that was the point. The multi splash page build up, Clark's rage boiling over, the speed of the battle, the mystery of Zaar, the mystery of Zod's motives, and Clark about to proclaim that this was what he was put on Earth to do, all point to this big hot-blooded ending that's side stepped by a sensible solution. Clark and the reader are left with, for lack of a better term, "blue balls." Dealing with that and refocusing was how I read the epilogue. The anti-climax was like a slap on the wrist/smack in the back of the head for Clark. That's how it landed for me at least.
