According to the tracks and rules of roller coasters it inverts you twice
(An inversion is at any point in the ride where a train is flipped over 180 degrees from the normal position)
But from a riders point of view it doesn't since it doesn't actually tip you upside down
Personally I am glad it doesn't take its passengers vertically down (the only position where the rider is upside down) because when I went on superman ultimate flight at SFGAv all I can say is going throughout the pretzel loop with that harness gives you a 'strange abdominal sensation' which can put you off your food for the rest of the day.
