It seems like you, and some other people, are misunderstanding a bit what of what went on in that scene.
It wasn't that council of side-characters was showing Kirito things that happened in SAO, instead what 2-nd best girl, Sinon, said is that they can only
scan Kirito's memory of what happened in SAO.
What they showed him, somehow I still don't understand how they had access to that, are records of what happened after SAO went off-line, after all Kirito never saw Oberon sexually harassing Asuna. And they did it to keep him busy as they scanned his memories about what went on in SAO.
Of course I can't say that I am 100% sure of what I am saying since, I didn't pay too much attention to the scene.
After all
