Kenji Tomiki described these exercises in his book "Goshin Jitsu" (1975), not his book about goshin jitsu no kata. They are basic exercises for his "randori" method which also can be used in a competitive way.
Just another view on it.
That really in my mind characterizes Tomiki's system - not the competition but the solo and paired exercises designed to improve ones overall aikido. Understanding the idea behind/within the exercises and then applying them not just to the exercises but the waza themselves and you are on your way.
