I seriously thought they meant "it's not possible to have a chess game with more than 218 moves"
Yeah, I'm still confused.
There is no reachable[1] chess position[2] at which a player has more than 218 valid moves[3] to choose from.
[1] Able to happen while following the rules of chess
[2] The arrangement of chess pieces on the board
[3] A valid move is the motion of one piece to a place on the board, which doesn't break the rules of chess - e.g: "King to E4."
