    the path of least resistance in this case is where the air ionized, when current starts flowing it gets hot, expands and raises, making an arc. So we could blame the weird shape to thermodynamic properties over electrical ones

      Exactly what happened here! In the video the arch starts in a much more straight line, and rises as you describe as the air heats up.
