Either way my comment still stands. Allies were still engaging axis CVs. We were still attempting to engage and sink the enemy (points wise the frame was NOT over, only objective-wise), so if they were ORDERED to screw around and capture bases they weren't supposed to (including Moresby, since Shoho was sunk), that's another matter. They could have, and SHOULD have been setting up strike packages for US carriers, defending their own, instead a number of CAP pilots on the USN side had a very boring frame.
You know you can't take Moresby, give up and move on. That's not the end of it. Why keep screwing around like that? Not only did it short-shift a lot of USN pilots, it gave IJN pilots nothing productive to do.
