Nuke, like AfterFX, stores position data as pixel value (ie in 1920x1080 picture, the center position is 960x540). so when You switch to different format, the position stays the same. This is even the issue when You switch-on Proxy-in-the-Viewer and draw the mask (nuke 8v5). after switching the proxy off, the mask doesn't resize itself info full rez.
Fusion stores position data as a percent of a picture / resolution, You're working with. So if You scale the footage, every element will stay as it was.. But it also has some drawbacks - mainly from implementation method in paint/tracker, imo.
I see, I think "Resolution Independent" is easily to be misunderstood in the context, haha

Though I have to say, I don't really see the problem for that to be honest. In AE, sure, in Nuke - not so much.
The only time I came around such a problem was when working on 2K source clips, and then getting the graded Clips later in HD and I have to apply the changes accordingly. So any Painting and Tracking etc does not fit anymore, naturally;
This can of course be fixed when you know up front the Grade will only be HD, or if you can ask the Colourist to just render at Source-Resolution. My workaround is a simple Reformat node though

Never had another case where this was a big problem, but I see that it could annoy at some point
