This is just ONE example of a fast slice serve.
A slow slice serve, like used for second serves, are usually hit upwards first, and the slow speed allows gravity to take effect and bring the ball back down.
Slice serves are not twist serves.
You keep insisting of using top level players hitting fast serves. You need to look at top level players hitting normal speed balls.
