I agree with this question. How was clean determined in the dataset?
Knowing how the word is used in chess is not enough to know where the line was drawn in the data here, which is the basis for the entire analysis shown.
This would mean that, in the case of "up 2 rooks for a queen," the board would evaluate to a player's advantage even though that player would tend to lose at the highest level. I think something weird must be going on.
