No - one spline towards the centre of the chassis - which is viewed from above and the rear would be to the left.
If you are running a full size servo - you probably won't need to do this.
We have to do it with the low profile servos because their output is moved outboard as a by-product of the low profile gear-train in their housing.
On zero trim, my Spektrum S6070 won't achieve a completely vertical alignment becuase vertical sits between two splines.
I always then choose the spline that moves the output arm towards the centreline of the chassis as opposed to the one that moves it further outboard.
