I think they mean acting as a write-through cache. If you send writes to the cache and have the cache delegate those writes to the underlying DB you get consistent invalidation, and if the write-through cache is smart enough it can even be transactional with the underlying source of truth.

Readyset does have some work and design done towards read-your-writes consistency, but it's still under development. The Noria paper does briefly touch on extending partial materialization with stronger consistency models via MVCC or other mechanisms as well.
