No, the organizations are a display thing only. They don't bring additional permissions.
Permissions to edit are per-collection.
How many "organizations" do you have?
Maybe you could have one "hidden" collection per "organization" with different permissions each, and then one public/visible collection that aggregates all the posts of the organization collections?
PS: if you can describe you use case in more detail, I would be very interested.
