Oops .. I accidentally left the word 'spin' in the above sentence (typo).
Apologies for any confusion.
They flip around in their terminology usage in the paper as well. Sometimes they refer to simply Orbital Angular Momentum (OAM) and Photon Orbital Angular Momentum (POAM), which makes it a little confusing as well. Both of these terms refer to the same property, ie: that induced by the rotating BH.
I yield to Rob's article .. much clearer.
