It *is* confusing but in actuality, it kind of works: It's a Windows Subsystem - as in the Hypervisor/VM platform - to boot a Linux VM. And, more importantly IMO, Linux distro is using this Windows Subsystem for: booting, drivers, and networking (.e.g. the "/sys/wsl" folder, and whether the Window Subsystem will generate fstab, etc..)
