How Can I quickly extract subD selected faces like right image?
If I could invert subD face selection, I can delete unnecessary faces instantly.
the example may be too simple object for the functionality.
If the object become complicated, I think invert functionality become worth.

Thank you for your reply.
Yes, gumball + option key works well although I have to move the object once.

ExtractSrf will also separate the SubD faces.

Nice again! 
I didn’t noticed the ExtractSrf command works with SubD faces.
This is also the solution.
