It actually doesn't hit 90 degrees during the turn. I think the highest it ever gets is 75 or 80.
The thing about G's...
Vertical is only measured vertically relative to the train....(obviously)...and lateral is measured horizontally...
So, if you change the track from 5.9 vertical G's to 3.5 vertical and 1.1 lateral, you still put the rider under 5.9 G's, it's just divided between two accelerometers. If there was a third G-force measure in the direction of the net G-force, it would still read 5.9. Although, if I did that, people who only look at the color of the numbers would not be commenting on it any more. It's not really meant to be real and I can't really change it now, so I won't.
Another reason why this ride isn't realistic....
Each wheel of a car full of people who weight 150 pounds would be under roughly 3835 pounds of force during the 5.9 G turn. This combined with 253 mph = destroyed wheel barrings.
