It's in the name, it's a "gain" control as in "to add to", if you add zero gain, you are left with the original signal - many don't even go as low as zero due to how they amplify (see non-inverting opamp amplifier) - they don't attenuate. Additional circuitry could be potentially added so that it does attenuate but that isn't it's job, it involves more circuitry and any caveats that come with doing so. Attenuation for hot signals is usually dealt with using a static reduction called a pad control.
