Minecraft wiki entry for Illusioner, associated text: These hover and waver at short distances from the actually invisible illusioner, though they do not space themselves out until the first time the illusioner is attacked. They face in exactly the same direction as the illusioner, and move somewhat in step with the original, appearing to no-clip through blocks like a vex does. Despite using the shooting animation whenever the original uses its bow, only the real illusioner can shoot and be damaged.
