The 4c eyes prime the solenoid earlier by recognizing that the ball is dropping at an earlier point. Once it sees the ball in the top eye, it will charge up the solenoid and then confirm it with the second set of eyes before firing. This is advantageous in making for a more consistent stream in semi since it is taking out some of the delay between each shot.
In burst mode it would theoretically make those first few shots run a little smoother before it kicks to burs mode(which isn't going to even be anything you would notice). Once the marker starts ramping however, it will be already priming the board at the appropriate rates to keep it consistent.
As others said theres no real benefit outside assembly. I just thought I would elaborate why if you were curious.
