there's similar move called chord grip reversal, but this on is done in the middle of 4 fingers, which is actually a real good one!

Thexxx1 must know. I already asked him 

[o0oDWDNSo0o]

I would call it single-handed-black-star....and I think Ricardo is the person to ask how to do it best....

[Milwaukee John]

That is an awesome trick.
 I'm  going to try to learn this .

It looks like a  variation of a rewind?

[ImThexxx1]

okay, This is actually 2 moves. haha 

Its a finger roll to a rewind, Then a second rewind to a finger roll
2 moves, put very close together making it look like a single move
He also used 2 fingers instead of 1 finger on the finger roll, But the idea is basically the same
here it is in slowmo, and broken into 2 parts

It very closely resembles a "Chain Unwinder" (very beginning).  The cool thing about those moves is that you can actually switch hands mid rewind as well as change planes or do "figure 8" unwinds as well.
