the green , blue and pink spots are not lined up with each other.

the 3 spots are not in a straight line so the ball would
experience a change in velocity if it did cross the green
spot and the blue spot and then it vectored to the pink spot.

however you can buy more pink spots and place another pink spot
on the table lined up with the other 2 spots and then they would
all be in a straight line.

or you could simply exchange the green spot with the brown spot
in the OP if thats the way you do things.
