That's rather poorly written because first it says to set pressure based on the vehicle manufacturer's recommendations and then it says to adjust pressure for the vehicle's actual weight... and these two values will not always be the same.

Technically the best way is to measure the weight on each tire, yadda yadda, but this usually isn't very practical, and the vehicle is not always loaded the same. In most cases it is best to inflate to maximum pressure (and thus provide maximum weight-carrying capacity) and be done with it. If you see excessive center treadwear (indicating overinflation) you can make an adjustment but usually that isn't a problem.
