Why can't AT just want to re-inforce it? Not like he'd lose anything by doing so.
Because it'd be pointless to reinforce something so set in stone as this. It's the same thing as Kuririn only mentioning that Cell is far worse than the androids to Goku, in the airplane, without bringing up 17/18/19/20. That's not a good reason to show these latter ones didn't surpass Freeza, because it's something already shown, and there's probably another reason Kuririn only mentioned Cell. Likewise, Piccolo standing alongside with Vegeta and Trunks being AT's way of saying "hey, you guys didn't forget that Piccolo isn't hot garbage as the humans, right?" serves no purpose and it's only unnatural.
AT had 2 statements that only showed Vegeta and Trunks behind Goku and Gohan were really of any relevance at the Cell-Games.
Piccolo doesn't need to be far weaker for these statements to just exist. He only needs to be weaker, which I never denied, but by how much is anyone's guess. Cell only mentioned Vegeta and Trunks as possible Goku's replacement because they are the next strongest guys (or at least according to Cell's guess), the same way Goku, after recovering from the heart virus, only mentioned that if Vegeta wasn't able to beat them, he wouldn't be able too, without referencing Trunks, who shouldn't be much different than Vegeta.

Papasmurf brought-up a good point of Piccolo needing a Senzu-Bean. That showed he really was damaged and not really even close to fighting on even-ground.
I don't remember Piccolo eating the Senzu. Vegeta and Trunks didn't too? The manga it's not so clear on this, but in the anime Vegeta ate a Senzu bean for sure.
