What are you talking about? Also, I will clarify my points and your points:
First, you said 7-3 Moro being stomped by MUI Goku is PIS and if Moro uses Energy Absorption, he will stomp MUI Goku. That's wrong, Goku wins via being massively stronger and especially massively faster than him and having Ultra Instinct on top of that. You can't bring 4-B Moro sucking 3-B Vegeta as an argument, because as I said, Vegeta isn't massively faster than him. Moro could keep up with his movements, therefore could suck his energy. Speed is the factor here, not AP. Moro can't absorb energy from someone that will blitz him as we have agreed upon.
Then you said UI Moro didn't absorb energy from UI Goku despite his power and speed are close to him is also PIS. That is because Moro could not absorb energy from Goku. He has to withstand Merus' power with his untrained body and that already takes a toll on his body. Even Goku himself says that Moro is at his limit, so the point is that he could not absorb any more energy, not because he could but he decided not to. And he could only suck Goku's energy after he fused with Earth but he was about to explode anyway whether he would absorb Goku's energy or not.
