Correct.  If you replace the rather generic names A, B, C, D, E with
something more specific like Urtext, EditionBrauer, EditionThoeni,
Layout, Midi, then it becomes more obvious that it's a nuisance if

\keepWithTag #'Urtext

will remove every music tagged with Midi or Layout.  Forming two
separate tag groups will cure that problem.
