Sequencing of Mat Exercises

Just curious - Many of the mat sessions on Pilates Anytime do not follow the exact order of the 34 Mat Exercises. I have been a certified Pilates instructor (East Coast) for close to four (4) years - Mat & Reformer. I carefully follow the proper Mat sequence for all of my sessions. I may do a variation of the exercises, but I still remain true to the Pilates' sequence. Please advise.
