Black's throw-in is tesuji.

:
White must capture, in order to stop Black from getting a large four-point eye in the right centre.

:
Black captures White's single stone above, also creating the second ko-shape in the right centre.

:
White descends to the upper edge, as "usual".

:
White starts the ko-fight at the right edge.

:
Black occupies a shared liberty.

Please note that if reverse-komi is (too) low, KataGo wants to indulge its passion of making a 100-point error with a ko-threat on .
The choice of such a favourite must then be manually corrected.

:
Black captures the ko in the right centre.

We have reached a position that reverts the the subvariation two moves earlier.
