You have --shuffle in use, so --load-list does not determine the order
of execution. Certainly for other test runners, or for test runs
without --shuffle, you could use the load-list files as an
approximation, *as long as* the test runner in question cooperates.
For your scenario here though, of being able to reconstruct what an
arbitrary run did, you can't depend on them. (Due to shuffle).

Yes, you'd be able to filter the run down quite easily I think.
