I'd gather that's the reasoning for the really long wheelbase. Those two front wheels being way out in front gives back the stability lost with the format. But the issues with getting power down in a reverse trike are harder to mitigate.
Now, this is a high power to weight ratio racer, I can imagine a reversed layout was considered, but a single (or narrow pair) driven rear wheel probably didn't meet the traction requirements for acceleration. Bare in mind this thing has one insane power to weight ratio. 631hp per ton.
I also imagine a clever differential will help this thing keep pointing in the right direction, something you lose the ability to have on a reverse delta.
Add to that your race driver doesn't need to re-learn car control skills, he still has two powered rear wheels to manage with his right foot that should work just the same.
So there's some reasoning why it is what it is, this is probably the only way to do a delta layout for racing at this level.
