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?

High-end power cord manufacturers are in a bit of a pickle: if the power cords do everything that's claimed--that is, if they somehow make up for the "problems" in all of the wiring coming from your local power transformer to your wall socket--then why wouldn't a run of 2 feet, or 1 foot, or six inches (requiring only an el-cheapo extension cord) perform the same miracle, thus cutting down on the price of the super-expensive power cord material?

The answer is in the last phrase of the question.
