4770 glitch?

Hello, level 4770 is a somewhat hard level. To pass this, you should destroy frosting at the first 4 rows. Then aim for keys. And last, combine special candies and trigger cascades to destroy all remaining frosting.

I still get 21 moves for this level, which is what Suzy Fuller got and she managed to pass this. If you watch this video to the end. It is possible with a lucky board and you don't actually have to remove every single frosting for this.
