I believe this is the separation of the transport layer protocol (QUIC) from the application layer protocol (HTTP/3). QUIC can be seen as a replacement for TCP. HTTP over QUIC then becomes HTTP/3 - with improvements in latency and head-of-line blocking over HTTP/2. So in that sense it will supplant HTTP/2 as QUIC gets adopted more widely.
