How does the Exploding Heads Community relate to the Exploding Head Nostr Account

I have noted that there is an Exploding Heads nostr account that has posted posts that do not appear in this community. Would it not be useful for those posts to be posted here as well? Otherwise, it seems that in order to have the full Exploding Heads experience it is necessary to both follow this community and the separate Exploding Heads account. It does not appear to me to be the most efficient way of doing things.
