I watched the video and I didn't see anything that I questioned. Looks plausible to me.
There would've been a slight pressure differential working on the window (slight suction outside, slight positive pressure inside), this would've bent the window outward forming a cut-line at the bottom of the window where it enters the door. It broke loose and some of the tint tore off as it went.
While tempered glass breaks and looks instantly like a jigsaw puzzle, it does still tend to hold together until acted upon by an external force.
