Forgive me for not giving more details on the post and video :)
So the reason for putting the iron in at mid-shaft is because that is where the first direct heat will do the least amount of damage, and where the hair curls less. So you want the heat to hit there first and stay the longest.
If you start the iron down at the ends you are putting all the heat on the ends of the hair and for the longest amount of time. Causing damage, and as the hair builds on the iron the heat isn't able to reach the rest of the hair shaft.
The top of the hair shaft, the "roots" are the newest and most delicate part of the hair. The virgin hair as we call it in the industry. So you can start at the top of the shaft but you also don't want to damage that hair too much either. You could end up with breakage right at the roots and that would just suck.
I hope this additional info helps. Any more questions don't hesitate to ask!
