Relevant log output for that particular case:

Note that the online IDs are swapped.
After https://github.com/ppy/osu/pull/23362 I'm not sure the
`LocallyModified` check is doing anything useful. It was confusing me
really hard when trying to parse this logic, and it can misbehave (as
`None` will also pass the check).
