I'm guessing here, but among the reasons may be:
1. It allows the frame to be shorter, which lowers cost of materials
2, It makes the trike more "nimble" (ie - smaller steering radius).
3. It probably allows the distance between the front wheels to be shorter too (so turning does not interfere with the pedals and/or the frame). Smaller distance between front wheels means easier to fold, store and transport as well.
I'm sure there are other reasons.
