Author here. Thanks for raising this. I posted a comment. Maybe you can help us reproduce.

QUIC does not depend on UDP datagrams to be delivered in order. Re-ordering happens on the QUIC layer. Thus, when receiving, the kernel passes a batch (i.e. segmented super datagram) of potentially out-of-order datagrams to the QUIC layer. QUIC reorders them.
Maybe https://blog.cloudflare.com/accelerating-udp-packet-transmis... brings some clarity.

Note that I (author) made a mistake. We (Mozilla) recently raised the minimum Android version off of 5. See https://blog.mozilla.org/futurereleases/2025/09/15/raising-t... for details.

4 Gbit/s is on our rather dated benchmark machines. If you run the below command on a modern laptop, you likely reach higher throughput. (Consider disabling PMTUD to use a realistic Internet-like MTU. We do the same on our benchmark machines.)
