So WSL1 is reverse wine basically?

Nope, WSL 1 uses pico processes, a technology based on Drawbridge research.

It is a bit more advanced than Wine, with first class support from NT kernel.

Whereas WSL 2 uses Hyper-V, which is a type 1 hypervisor, all OSes run as guest, including Windows itself.

Not _exactly_, but it's a pretty close analogy. Certainly moreso than WSL2 is.
