Hi!
I don't know if you find it in the Card College series too but at least it is described in "Card Manipulation 1-5" by Jean Hugard (book) on page 46. I don't know how similiar the technique is to the one used in the ego change but at least Garcia is claiming the rights to the ego change so I guess it is a technique of it's own. The effects are quite similiar. I'm sure Stevebo can help you out if you got more questions about this.
