Either way, you don't need an axle running the length of the robot. Its just wasted weight, and space.

there are two possible reasons that i can see for this:
1) there is no frame outside of the wheels, so if you used two independant axles, they would only be supported at one point, and the wheels (and more importantly, the sprockets) would be more vulnerable to becoming misaligned.
2) in addition to this, if the axles are beefy enough, they could be used to reinforce the chasis of the robot.
