Yeah, but I don't think the feat you posted i.e. "A weakened Thor kills a guy by punching him into orbit." was meant to imply he had superfast arms, it's a strength feat. In the same way that although Superman et al. fly when they pull a planet it's not a flight speed feat it's intended as a strength feat.
It could be argued that Superman's strength when tugging a planet is largely due to the strength of his flight abilities.
He was once attached to this machine that sapped him of all his physical strength, but when he realized he still had his power to fly he just flew out of there, bringing the machine he was attached to out of the ground.
