Not entirely true. The clutch disc still wears, and so the pressure plate either has to adjust or you get the pedal getting higher and higher before engagement. Think of it like a disc brake, as the pad wears down the caliper piston starts staying farther and farther out.
A self-adjusting pressure plate will compensate for this with a ratcheting mechanism (think self adjusting screw on a drum brake) that keeps the fingers down so far when they move to a certain point. Conventional wisdom in the US is that a self adjusting pressure plate cannot be reused because it will lock the clutch up, but in reality if you put it in a press and push the fingers down as far as they go it resets the ratchet and allows them to go back to the new position. We just don't do it because pressure plates in general don't get re-used in the US. This isn't the OP's issue since he bought a non-adjusting clutch.
So my question to the OP is "Why did you do that?"
Also I agree with 85,
