Yeah that's correct - every Fusion composition is a distinct entity. You're not the first person to be confused by this.
If you drag a Fusion comp from the Media Pool to a timeline, then edit it on the timeline, you now have two independent and disconnected copies of it. The same applies if you copy a composition on a timeline - or copy a clip that has a composition on it. Every copy will be independent, and any changes made to one will not affect any of the others.
This can be especially frustrating and difficult if you have a clip with a composition on it, and then later want to edit that clip, splitting it into two or three or more parts. You end up with 2 or more copies of the comp, now disconnected, and if you later want to edit that comp you would have to make the same changes multiple times - or change one, and then delete the others and replace with the copied copy. And then if you need to change it again in future, keep doing that over and over.
One of my wish list items for v17 is much better Fusion composition management. I hope they will increase the visibility of Fusion compositions, so it's possible to clearly see what comps you have where, ideally with a reference to every composition stored in the Media Pool. And I hope they will provide better composition management, for example a way to put the same composition on multiple clips, such that all the clips are affected by changes to a single comp.
