Nack asked if XG makes slightly unsound shifts and multiple slots

Back in June, Nack asked:

Is it possible that bots have a built-in bias towards slightly unsound shifts and multiple slots (that modern players try to mimic) in preparation for a shot that somehow don't correspond to real equity? (For example, it might sometimes make less bold plays than it should for the opponent that don't take full advantage of the player's temporarily compromised board.)

At the time, I mentioned that XG 3-ply is a donkey in this sort of situation, but I didn't have any examples handy. Below is an example that I ran into recently. XG 3-ply plays 13/10 13/8 here, which a rollout says is a double whopper with cheese.

Match to 7, White leads 2-0
Blue to play 53

White	87
Blue	107
