It means everything local and P2P, with no relays, or relays that don't allow for storage.
It's great for some communication and terrible for others. Best would probably be allowing for both channels, so that we could decide per use case.

The other defining feature about distributed architectures is that no information is held uniquely in one place. There is usually massive duplication of the information and a negotiation algorithm to determine which version is correct. Fortunately in Nostr the latter problem problem is solved by digital signatures.
Like with blockchains.
