I think what he's saying is that Pacquiao *might* have problems cutting weight at his current age. I think at 140 he wouldn't, but lower than that, then yeah definitely Loma takes some advantage.
I don't know why people are so confused about this. Pac has been hurting/dropping tough ass men weighing over 160 for close to a decade. He would put a serious hurting on Lomachenko. I honestly think 1 left hand would have Lomachenko down and out or severely hurt. Frankly, Pac retires him.
