It's a different style, you could do that then roll it up the other way to how he showed. Afterwards, roll the snake roll into a circle tucking the ends in then flattening it. That would also give more layers. If you wanted the green onion throughout the layers you should probably roll it out thinner and apply the green onion across the whole surface to roll up instead of just in the middle like he did.
