It seems like that is the more conventional configuration and would allow for smaller and lighter packaging.

Honesty, the main reason is we had 6in mecanums lying around, and this is our first prototype; we just wanted to see what building a more complex drive train was like. But there have been some good points mentioned in the thread, and mine was if something went wrong, we would be able to default to casters.
