"Research supports this" but that research might not be relevant to the use being discussed.

The general case is where a vehicle is coming up to a cyclist from behind. The "travel vector" in that case is pretty-much a stationary object in front of them.

The idea of flashing lights is to be noticeable (conspicuous) from a longer distance. Flashing lights are much more noticeable than solid lights of similar size and power).

If the motorist can recognize the object as a cyclist, they can make reasonable estimates of speed and direction.

By the time they need to pass, the headlights should be letting the motorists deal with "travel vectors".
