Any idea why they're all pointed in the same direction, rather than different directions, in photo 4/10?

You don't want to scan two angles at once. Direction is determined by probing different angles, not by the difference between two angles.

From the article, it seems like the four horns on each individual unit are enough to do the triangulation.

Looks like San Francisco, so I assume it's an exercise and perhaps they're all tracking the same friendly plane.
