Why three motors?

Can someone enlighten me on the wisdom of having a three motor turntable like the TW Acustic with only ONE side of the belt touching the platter?

Here is an example.

I just don't get it...

This becomes minimized significantly whn you use a silk string, or tape to drive the platter. There is a noticeable improvement in PRAT and a much clearer sound over rubber.

However I'm not certain that you would get adequate "gription" with either silk thread or taps in a 3 motor version. There's just not enough surface area on them for such a small contact area on the platter.
