iTunes Match would acoustically match songs, and then if the match failed, would just upload the song to iCloud as-is. I imagine maybe this behavior is intended to replace uploading the song if the song doesn't match? It'd explain the situation in the quoted tweet where a live Phish show got replaced by a live recording, assuming that it failed to acoustically match and iTunes resorted to a metadata-based search instead.
