A shifter would accomplish that without the need for an extra wheel.

Smaller wheels will give you more torque. Think of a wheel like a pinion on a rack, except there is no teeth. IF you reduce the pinion size you get more torque but less speed.
Is this the completed assembly? Another guess of mine is that in addition to having different speeds, based on which wheel is touching the ground, you could have different wheel bases. So basically, in one orientation(likely the one with the higher speed) you have a smaller wheel base, therfore you can turn easily. On the other hand, when the other wheel is touching the ground(likely the lower speed), you will have a larger wheel base and therefor it will be harder for you opponents to turn you.
