Kettlebell Swing form

[Shavleg]

Hello, I recently came across the video which showed that swing should be performed without twisting, as it was very dangerous for the back
I know basic guidelines to perform the swing but I was wondering if I was doing something wrong unconsciously and was not performing correctly.

Here is the video so please review and give me advice whether it is correct or not

First time poster so I did not know where to post, if it is not the place for it, I apologize.
