It only cycles between two targets are within range. Try putting a heavy gunner at the edge of your base and use your Gogo bar to spawn two flamethrowers. You should be able to observe the Gunner switching between the two gunners.

Keep in mind this only will happen if you've made the upgrade, applied it to the schematics, and *then* applied it to the gunner(s) defending your base.
