what's so special about this drill? *shoulder flex*

[Laban]

I really like the 'thegymnasticminute' youtube channel - they mostly publish good stuff, trying to give the best advices in the shortest time.

They posted this video (not new) showing some shoulder flexibility drills - and I was wondering about the first one, the one with the aerobics band - what makes it any special or good that they decided to put it on? I trust their judgement on picking the best stuff so I really wanted to know whether this specific drill has some extra 'virtue' or was just a random pick?

the video : YouTube - ‪Developing Shoulder Flexibility - Tammy Biggs‬‏

thanks

actually Laban, that one should be avoided until a coach finds the need to do it. and it should be done under the supervision of a coach.
