This design reminds me a little bit of the "evmap" Rust library which implements a lock-free HashMap -- it also works by storing two copies (one for writers and the other for readers) and swapping between the two after all the existing readers are no longer in the middle of a read. It's a pretty cute idea.

It’s very much reminiscent of double buffering in graphics programming.
