That is true, but they use the blower because it is a 2-stroke motor with reed valves. It would be pretty much impossible to get an intake charge past those reeds without the roots. The turbos on them is just a huge bonus.
And to the OP, it really isnt a great deal for automotive applications. A simple turbo only setup will provide plenty of useable power. But on a car like the cobra or lightning, which already has the roots and it is at its limit, adding the turbo setup gives you a power potential that is insane. This allows you to really intercool the main charge before the blower allowing alot more boost/timing. Though many feel that a simple blower upgrade to a big 2.8 or 3.3 whipple is way easier and more effective.
