CCleaner for Windows

I'm just curious, why is it there are always multiple scans for registry required, and why is that they are always lower and lower numbers of items found?

Thanks;

If a registry key references a broken key, or that key references a broken/missing key it is not detected. Those keys are later removed by CCleaner, making it possible for further errors to be detected in the next pass.

I see, so is it simply by averages that there's apparently always a lower number of broken/missing keys found on subsequent passes?
