They don't. These are not truly examples of things traveling from Point A to Point B. No information is being transmitted FTL. It is not clear to me why the author sees this as confusing.

Imagine you have a device with two lasers (Laser A and Laser B) that each point down to a white surface. The lasers are one meter from one another, and are calibrated such that Laser B fires exactly 1/(600,000,000)th of a second after Laser A. It might look that the dot is moving faster than light, since light travels at 300,000,000 m/s; however, as we know, nothing went from Point A to Point B.
