Because you let it be shifted two times before selecting your tag? Your
music does not contain two _copies_ of note, but rather contains note
_itself_ two times. So \relative is applied to the same music two times
in succession.
Use #(music-clone note) or #(ly:music-deep-copy note) or $note for your
two uses, and the note will get placed in two separate _copies_ of the
original rather than using the note object itself in two places.
