It seems that applies when you increase the LED current (which will make the LED brighter) but use PWM to keep the total power dissipation within the LED's limit. Which is not what you said.Yes, perhaps not always recommended. I read it belowReally? Do you have a link to the article, because that sounds bogus. Even if it isn't bogus I wouldn't suggest that it is "always recommended".But if you do use those pins I read an article that your eye actually sees the LED brighter if you use a PWM to drive it rather than a steady voltage, so doing this is always recommended.
You might be getting confused with multiplexed displays, where each LED is turned on for a fraction of the refresh cycle, but at a much higher current to compensate for the fact that it's only on for a short time. Persistence of vision makes the eye see a less bright LED which is on for the whole time.
