As you said, they recreate episode fights but they also allow for us to sometimes see new cards that aren't released yet like Tetsuya using Eligos against Terumi or when EB02 was first announced we saw the effects for Demonic Spear, Swirling Darkness, Cerberus Ace, Bold Retaliation, and Fanged Dragon Declaration. It's great for knowing what's coming up without having to wonder too much about effects when the anime doesn't display stats or name all conditions and so on.

As for the people, I'm not exactly sure on them. Perphaps someone else more knowledgable can answer that for you.
