Pros are choking up on the paddle for faster hands at the kitchen. How do they switch to a two-handed volley out the air so quickly?

I know pros have been choking up on their paddle handle for faster hands but it just confuses me how they switch to a two-handed volley out the air so quickly. I would think that choking up with their dominant hand would leave little room for their non-dominant hand when trying to switch to a two handed volley.
