refer to virtual users and anonymous users in the same paragraph, so I think you are correct.
This paragraph appears to support your conclusion:
virtual_use_local_privs: If enabled, virtual users will use the same privileges as local users. By default, virtual users will use the same privileges as anonymous users, which tends to be more restrictive (especially in terms of write access).
Frankly, I think "remote users" would have been a clearer term, all other things being equal.
