Yes, if I remember correctly x265 just adds the metadata for each frame encoded, scene related info is ignored.
At the time of development (possibly now too), HDR10+ titles also have metadata inserted at every frame, and not like 1 SEI message per scene.
After all, some of this is trial and error using x265 as "correct" implementation.
There is still some desync between source JSON and extracted where there is a metadata change (scene change?), but it's usually just 1-2 frames that are different.
