No that is good enough. He couldn't finish the fight like that, his health was in jeopardy and the stoppage was warranted.

It's what would have happened were he not cut.

The problem comes about because the cuts were NOT caused by "clean punching". It happens, it's boxing and unless it's completely blatant it's not called foul. But it definitely lends to interpretation.

Viewing the event as a whole, that needed to be a rematch!
