Yeah, that sticks out like a sore thumb in an otherwise accurate article. Antennas have a certain radiation pattern for transmitting, but there is also improved reception in the directions it radiates strongly in. With wifi, there is usually little you can do since you probably want a spherical radiation pattern, which prevents you from getting any significant gain over a perfect isotropic radiator, but that's a different story.
