If only they had appended "to choose from" to the article headline, it would have been clear from the start.

The caption on the first position is "Reachable chess position with 218 moves for White, published by Petrović in 1964."

And the title is unambiguous: "There is no reachable chess position with more than 218 moves" -- that cannot possibly mean "There is no reachable chess position that it takes more than 218 moves to reach". Also, lichess is a chess site, where people are certain to know that chess games can go way beyond 218 moves.
