Is there a minimum length for power cords?

A cable manufacturer's website states the following:

"However, any length shorter than 1.8 meters (5.9 feet)will begin to degrade the effectiveness of the shielding and filtering capabilities; regardless of who is the manufacturer. Power cords are not like speaker cable and interconnects where shorter is better."

Does anyone have any thoughts or experience as to the validity of this statement?

Who's cables are we talking about here? I don't think anyone mentioned any brands up to this point. I'm guessing that the OP is referring to Shunyata, but it would be helpful to know for sure because I'd like to see if other manufactures give the same reason for the cables sounding better at a minimum length.

Why would length make a difference whether it's a power chord or speaker cable?"

With speaker cables and IC's, popular opinion is to keep the runs as short as possible to get the best sound quality. With power cords, some feel that the cable needs to be a minimum length to get the best sound. Personally, I find the idea plausible, but I don't feel I have the experience or the technical knowledge to make a recommendation, one way or the other.
