The power meter doesn't need to be accurate, it has to be consistent, but that isn't what the author was trying to convey. It's a statistics problem.
Even if your meter is dead on every time, your body isn't functioning the same every time. Your position is different every time regardless of how careful your setup is, your speed measuring device has error (even a GPS) that varies from day to day, and the road surface conditions aren't the same. That's if you are looking for gains in speed for reduction in watts. If you are looking at FTP it is even more meaningless.
A +- 5 watt change is nothing more than data scatter under those conditions and should be ignored.
