Correct.

[He nods, and then after a little pause...] Though... a move is always a little stronger when a pokemon is using their own type of move. For example, Linda has a lot of normal and a water move she knows, but those, while they do give her a lot of variety, will never be as strong as lightning is to her. Because electricity is her birthright.

[And he smiles, warmly, at Ikki]

Does that make sense?
