That tree closest to the centre looks nice and straight to me. Makes sense that LR would choose this for that image.
Again, the scene is extremely complex. How is LR supposed to pick that one tree out of that entire scene and decide it is the one to base the entire correction on? The auto setting works when there is a clearly defined horizon or obvious horizontal or vertical features like buildings, etc. You can't expect an algorithm to be that judicious. Humans still have to provide some input once in a while.
