Pretty sure they're explicitly suggesting indirect fire, actually. Base station fires at mirror, and drone uses mirror to reflect laser to target. There might be stability problems, angle-at-which-it-hits-the-weed problems, and more-laser-scattering-due-to-longer-beam-path problems, but line of sight itself should be fine since the drone is up in the air.
