I think he meant Seiya wasn't originally a Gold Saint, although in this episode, it's made pretty clear that by the time Mars attacked Athena, he was the Sagittarius Saint. Mars even compliments him with "as expected from a Gold Saint.."

Regarding the scan, it's interesting how they're willing to bring back even minor characters like Geki and Ichi. I'm thinking that, along the way, we'll see everyone who survived the Hades arc.
