No, he's talking about how FH used the later 50mm Panzer 3s which were nearly non-existent in France, the majority of the tanks being Pz1, Pz2, Pz3 with 37mm, and a smattering of Pz4C/D. Because of the 50mm, the french CharB1 and Soumas on the map were not as powerful as they should have been. So he's saying that that only way to have a really good tanker map, that's authentic, for 1940 is to have the weaker german tanks.
