I don’t know what is happening here.
This girl set the pins on the squat rack. Then she moved the bar down to the pins. She ran off and grabbed a bench and put it between the squat rack and the smith machine. She then took the bar out of the rack and placed it on the ground. Then she put the bench in the squat rack but over the bar. She kicked the bar out from under the bench. The bar went on top of the bench, balanced perpendicular to the bench. Then she put 25 pounds on one side. This, of course, caused the bar to fall off, which confused her. So she got some help and loaded the bar to about 100 pounds with no collars and took it out for a triple of RDLs (with wrist straps of course) at the same height as the pins. This absolutely floored her. She did it two more times and then took the plates off, placing the bar on top of the pins, with the bench still in the rack, stuck under the bar, and walked off.
