the uli#3 stretch question

I have been to the hiller.dk.com site to read up on the ulistretch and I still don't understand the squeeze 5 times then repeat thing. Do I use the same hand or do I use the same hand and slide up or something. I have almost read the entire site but still do not understand this(and don't want to hurt myself). Please help!!!

had A mistake on the post. (do i use the same hand or the other hand to do the squeeze).
