Seems to me that it’s another part of a fingerprint for a user that can locate them, and possibly place you with others in the vicinity who have ID’d the same audio. Retail outlets have playlists that could be ID’d, possibly with enough granularity to indicate your path through a shopping mall or your dwell time in a particular department. I know the recognition is done on-device for some percentage of tracks, but it’s been unclear to me what happens to the running tally of times/locations/tracks identified afterward.

It's not sent anywhere or even stored locally on the device. Some people view that as a missing feature, actually, so there are apps that add this functionality[0], so you can review the songs you heard and find it later.
