Looks like there is no mentioning in the blogpost of the paper (poster) [1] in which the two-level broadcast idea is proposed.

It seems very similar to an earlier paxos optimization called 'pig paxos' https://dl.acm.org/doi/10.1145/3448016.3452834

The cited paper is indeed foundational, introducing not just two-level broadcast but also optimizations for validator selection and network topology that RaptorCast appears to build upon.
