Why would reversing AC leads reduce hum in a component?

I'm reading the spec sheet for the Parasound Z-Phono and they indicate that it has a switch for AC polarity to reduce hum.

I have a phono stage that hums (sometimes, always??) and I am wondering if that is a good solution? However, I also would like to understand the possible mechanism behind this??
