Actually no that's not for running Metal on another OS, it's for using another API called Vulkan on Mac.

Vulkan is a new API that is in some ways a kind of successor to OpenGL in that it's meant to be cross platform. It's very new though and drivers don't seem to have reached maturity yet. Another big hole was no Vulkan implementation on Mac/iPhone but that's what MoltenVK is meant to fill in.

It might be a good choice like 10 years from now but it's difficult to reach the same level of driver quality on Windows as Direct3D has.
