I have both, but cant remeber the names of all the routines. However, if you are refering to the effect where the cards are 'folded' until you have one pile of face up and down cards. then it is the same principle.
However, degrees of freedom is a much nicer use of the principle, and along with this you get a number of very nice effects.
So the answer is yes, its similar, though you should still buy the book, it is fantastic.
