You are confused about the order of operations it would seem. \relative
converts the contained music to absolute music, taking note of things
like \resetRelativeOctave and other stuff inside.
\keepWithTag removes some of the contained music.
Obviously you want to _first_ remove the tags you are not using, _then_
convert the resulting relative music to absolute music.
Try this:
\version "2.26.0"
testNotes = {
\tag #'testTag1 {
c1
\tag #'testTag2 \resetRelativeOctave c''
c1
}
}
testNotesB = {
c1
\tag #'testTag2 \resetRelativeOctave c''
c1
}
\score {
\testNotes
}
\score {
\relative c' \keepWithTag #'(testTag1) \testNotes
}
\score {
\relative c' \keepWithTag #'(testTag1 testTag2) \testNotes
}
\score {
\relative c' \removeWithTag #'testTag2 \testNotes
}
\score {
\relative c' \keepWithTag #'(testTag2) \testNotesB
}
