I'm not sure I understand exactly what you are asking, but I think neither is true.
Many MCTS programs read ladders as part of move generation or bias. For example ladder status may be part of the pattern data used for move bias in the UCT tree. During play outs, some programs use ladder status to select the move to play. For example a local response to the last move might be "If the last move put a stone in atari, play in the liberty of the stone in atari, provided it is not captured in a ladder". Many Faces uses ladder status in these ways. I don't think a program should play out the ladder in the play out, since half the moves are very bad.

This question has been hoovering in my head for a while and I wanted to take the shortcut to ask here :) Thanks, Chun
