Question about the twist

Sorry if this is a dumb question, or one that has been discussed heavily. I am wondering, is the 270 degree twist only on the way down, or is there one on the way up the tower also? Again I am sorry if this has already been answered.

There is only a 270 degree twist on the way down ... you can see really well just how it twists in this pic. http://www.virtualmidway.com/mystery/attraction517_big.jpg
