No, the instruction that he is referring to does not teach what top players play, nor has any top pro been produced by that system who can be verified. It teaches things like count to 5 after the bounce before hitting the ball, a very short and late backward and forward swing which produces no power, pulling back at contact which is never done by the pros, etc. It also does not address the things they really do and the complexities in that, but instead has some vague phrases which are of no use like feeling the ball.
Don't get taken in by any of this.
