Windows while Hyper-V is enabled runs atop Hyper-V VMM as a VM, same ways as Linux running as Xen Dom0.

WSL2 uses Hyper-V, so Windows running WSL2 is running on Hyper-V, not bare metal. Being a different VM than Windows “Dom0”, Linux Kernel in WSL2 would have direct connection to Hyper-V virtual ethernet switch. I think that’s what is happening.
