In my experience, a young pitcher who has the wrist cupped, curled, or pointed toward 2nd base is going to have something radically wrong at the bottom of the pitch during release. They will twist the ball instead of snapping it, creating bullet spin. Or they will turn the hand over the ball, creating a top side spin like action.
For those that have the Gillis Instructional DVDs, he actually suggests cupping the wrist on the rise ball. He suggests doing so puts the pitchers hand in a better position to get under the ball at release.
