drawing with your non-dominant hand theory

So I happened to remember this particular artist back when I was still in deviantart. She was so good at the age of 13 or so, and that was around 2008.

What I actually remembered was her journal: https://www.deviantart.com/melllorine/journal/How-to-practice-xD-237759164 on how she got gud after switching to drawing with the non-dominant hand, then back to the dominant hand. It has something to do with left/right brain drawing

Thoughts on this? Any anons with similar experience?
