Here is what ArduCopter’s lead control loops designer @Leonardthall thinks about a similar motor twist:

Tilted up arms are for aircraft that have crappy flight controllers where you are happy to be able to just hover in perfect weather. (I won’t tell you how I really feel ) Yes this is correct. It helps the aircraft quickly take up the additional constant loads. If possible yes. There is absolutely nothing good about tilted up arms/propeller disks, so there is never an excuse for that. Soft propellers blades reduce the shock loads on the airframe and motor in particular so this…

Yeh lots of people make that mistake. It all comes from the early DJI aircraft. But even DJI have sorted out their flight controllers so they don’t need it any more.
