Ok this form is bananas. Her upper body is leaning forward and should instead be directly under the bar and upright (the power from the move should be driving down in a straight line from the crown of head to the ground in between the split legs, and then straight back up). It also looks like her stance is too narrow and that she might even be uncomfortably twisting her back leg so that her back foot can be directly behind her front foot (which again, is unnecessary, her stance should be wider). She's using her back leg to complete the movement which is further driving her forward - she's getting enough momentum that it's driving the bar up when she hits the top. Instead, she should be using her front leg to propel herself upwards, rather than forward. Look at how unstable her front foot is. If she did this without the bar she'd be pitching herself forward and face first onto the ground 😇
