If you have only seen one example of it, and the guy is not the one who won your class championship, I'd guess he either thought it looked cool, or, he has some theory he is testing out.
As far as drag racing aerodynamics in general, in my mind, I see it as a balancing act. Anything you put on your cars body is going to create some type of drag which will slow you down aero wise. But if you are able to create more down force with it, and can put more power to the tires, overcoming the drag and then some, then there is a benefit for you.
I think the trick is to create just enough down force on the rear tires to keep them from spinning at full throttle while going down the track. Too much down force is drag and slows you down, too little, and you spin the tires.
Directional stability is obviously a concern for safety, so aerodynamics can play a large role here if things get unsorted from mid-track on when you are at high speeds.
Here is a little reading I found for you, I'm sure what I'm saying is nothing new to you.

That is a good point could well be, well there have been lots of these bodies made, I think its just preference as some have no spill plates (like were going to run) some have two side plates, some have this one in centre, so I think its more of a personal thing.
Were going for none as this body will be 1000% better and more stable than our last and no spill plates means little bit less drag.
