I have a feeling that a lot of these things are merely rumours spread by those who have their agendas. It could simply be that he really believes that SHE doesn't want to continue living under these circumstances. I know I've already told my loved ones that if ever, god forbid, I am in a state where I cannot communicate, and I need machinery and/or some medical apparatus to remain alive - than please, pull the plug and let me go in peace. (but obviously, don't let me starve to death!)
