It doesn't really say that. Let's say you are prepared to risk 1 percent of your equity on a single pair and you break that risk down into three smaller portions of .33% risk each. You're able to average down in a way where you are still only risking 1 percent of your equity total whilst bettering your overall position.
It's quite different from averaging since many traders do would be an interesting concept in case your system can er to it.
