It seems to me like semantics rather than a meaningful difference (for non-golfers like me, anyway), but Amanusa's course "lies adjacent" to the resort (presumably with separate ownership), versus the course at Amanera being a part of the resort.

The newly-renovated Bali National Golf Club, recognised as one of Asia’s top five courses, lies adjacent to Amanusa and offers a driving range, putting and chipping greens and a pro shop. Designed by Robin Nelson and Rodney Wright, the championship 18-hole course enjoys a scenic seaside setting. Amanusa guests will enjoy a priority reservation system at the course and may sign all charges to their Amanusa account.
Presumably the benefit for golfers is that Aman will have complete control over the guest experience at the course (rather than sending guests to a course that they don't own), though I have no clue what the differences will be in practice.
