“Recipients” and other strange language on Collaboration page

A snap’s “Collaboration” page says:

1. “You can collaborate with others administering this snap by listing recipients directly.”
    - Recipients? Recipients of what?
    - Directly? How would you list recipients indirectly?

2. “List each recipient explicitly”
    - “Recipients” again.
    - How would it be possible to list them implicitly?

3. “Share only with these people”
    - As opposed to what? Share with these people and who else?

What you should see:

1. Something like “Collaborators can make new releases, promote between channels, and other administration tasks.” (or whatever are the most common and most surprising things they can do)

2. “Collaborators for this snap:”

3. “Save Changes”
