Because he's from Belgium.But even the stuff w/kg is not true. Remco didn't do better w/kg at the vuelta than Vingegaard and even pogacar at the tour.
He did some good w/kg on one week weak races like tour norway. It's not the same thing.
Remco barely dropped Mas at last vuelta. The difference on general classification between Mas and remco was the iTT, and that's a fact.
How can you with a lot of confidence say that remco would beat pogi and vingegaard when he wasn't better than Mas in the mountains. It doesn't make sense.
