We stayed in the infinite verandah on the edge in Feb/23. The A/C turns off when the window goes down, not when the bifold doors are open. And the A/C only comes back on when the window is closed not when the bifold doors are closed. I think what he is referring to in the video, is that if your room is cooled down, you can open the window and by closing the bifolds , the inside portion of the room will maintain its coolness longer while you are enjoying the veranda portion with bifolds closed. Hope this makes sense
