There's an analog in machine chess. According to the research paper from 2017, AlphaZero considered ~10,000 moves per decision, 1,000x fewer than Stockfish at the time. h2h it beat Stockfish pretty badly.
Im not sure where the misunderstanding is.
The article says better players calculate a similar amount of moves and your anecdote shows the better player calculating a lot less.
So yeah it rebuts but the idea that GMs analyze more moves but it doesnt agree with the article, right? I guess just in the sense that its not more.
