Satellites by definition are from far away.
Telling someone you punched Thanos three times isn’t going to tell you the other person could have gotten him. Let alone everyone was moving around fighting aliens and dodging fire. How many accounts of what everyone else was doing would there be unless you were right next to each other?
I mean it’s just a clumsily written scene.
debriefing .. fables .
if that happened in real life the PTB would document every single thing that happened, blow-by-blow to try and learn from it, just in case something happened again. it's only 8 episodes right? at 22 mins each that's what? around endgame's run-time? they don't have as much time as you would imagine to go into detail, which is a shame.
when you step back, you realise that for all the framing, the story is limited in scope - like Thor 1 was. very few sets, very little outdoors; but that's understandable.
