I think its a confusion of terms. You could put 8 blades on the spindle. Thats in its self, doesn't change the tip speed of the blades.
I am not saying that the RPM is increased, but if you think about the tip of the blade passing a stationary point and then count the time till it passes that point again, you are cutting that time in half by doubling the blades. Think about it.
