I believe that to be true as well. But for the life if me I will never understand why Greer would err on the side of death in his judgement to let Terri be murdered, whether or not she was PVS.
There are many reasons. But all of Greer's decisions in Terri's case big and small were so partial to Schiavo, and his ties to so many of the players on that side were so strong, there is no doubt IN MY MIND, GREER's motivations had anything to do with FAIRNESS and JUSTICE.
