In before, yes, the film shows the 80 light-years of light's journey. The observer cannot stand still and see the light arrive; the observer was not yet born when the light left.
The limits of refraction and distance diverge would not allow the image to resolve to anything but very faint scattered light. Even at much smaller distances, this prevents us from seeing all but the biggest objects from Earth or even space-based optical telescopes. We will never see a flag or footprint on the moon from Earth telescopes without seriously changing physics.
True, that's why I used the term "light" to correct the example in video.

Yup. My comment was just to add on and reinforce your assessment of the correct results.
You know I will never argue with an alien of your rank.
