The purple thing is an overlay... There's the ramp, the three lanes (with lights), three blue mini pop bumpers, and then the ball drops into the inlane for the left flipper.

The kickback puts the ball into the left orbit, which is at ground level, the ball will hit the spinner and then IIRC cause it's outside the crop, it goes into the lanes at the top of the playfield, and into the pop bumper area there.
