Teach me more about this technique and how it works and helps

Could you please clarify that the goal is to see one single string in and out of each bead? (As for example, the green bead appearing as if two separate green beads leading into the next bead and then two separate strings heading out of the green bead into the next bead and so on?) Thank you!

ive not been able to find this anywhere but i see you doing it with your glasses on. So this is ok? doing the exercise with your glasses on? i was doing it without my glasses but i found it slightly difficult getting the last bead to split so to say - i have managed to get the last bead to get that v showing 2 yellow bead and 2 green bead but doing it wit my glasses has been much easier and quicker. also i thought that max time was 5 mins? ive actually been doing the exercise for 6-9 minutes (3mins per bead) is this bad??
