Oh yeah you're right of course. It can still affect the AI playing strength though, because it won't **instantly** know to just treat that position as a loss and back-up a loss. There will be a (potentially big) subtree below such a node, which an algorithm like MCTS will spend time in with multiple random playouts, each of which can also take a longer-than-necessary time.
