In tournament time control it may play the same move because it even has not
enough time to know that it is losing so it does not change the fact that the
level of game is higher than tournament time control.

You can also ask the same question about a regular tournament game.
If you see at move 40 that you are losing and you have only few seconds to the
time control.

I will prefer to play a move that I have not enough time to analyze in this case
