The coaster has 2 launch systems. My guess is that it launched from the one right out side of the station (one pictured in other posts) traveled around a banked curve over ground traveled back into volcano to next launch. The launch failed or didnt give complete power, the train started to go up the mountain slowed then rolled back hitting first set of brakes too fast brakes broke apart causing debris. Second set of brakes engaged and worked leaving them out side of moutain which is im guessing 15-20 feet off ground (not sure never really paid attention cause its going too fast). Why the PR said remained upright im sure is because of the banked curve that they did not go all the way back to. I have season passes so ill try to go and take pictures sometime soon. Maybe it will be open and ill try to take a video.
