Yes and no. Theoretically, that's the work of the UCT part. But, as Steve pointed out, kos can go on for long. I don't know what depth is attained in the tree (by the way, I would really like to know), but I doubt it is that long. Moreover, some kos must be kept for later. Hence, some basic understanding of kos in the playouts might be useful. That's merely a variation of the horizon effect. We could even imagine a situation where the UCT makes a threat that loses points in the only aim of having the ko past the horizon, where it would be 50-50 (for example) in the playout.
