The Reg SHO list only covers some of the FTDs in the system. It doesn't account for the ex-clearing FTDs which some claim are five times the number that the DTC records. So even if AURC is off the list there could still be a substantial number of phantom shares out there.
I hope you meant rise in the PPS rather than POS. All we know for certain is that the PPS will go up, down or sideways. Don't mention it. :)
