I think you've hit on the real point here. The problem is what were Mrs. Schiavo's wishes? There was a lot of conflicting evidence. If everyone agreed that her wish was to forego nutrition/hydration, I think there wouldn't have been much of a story. The problem, for me, was that the only evidence of her "wish" was irreparably tainted by the husband's conflict of interest, the contradictory testimony during the malpractice case, the fact that he never mentioned her wish for the first eight years, etc. To me, that really is the issue. Now, in this case, it sounds like this woman has a written document to "decide her own end care" and it isn't being followed. In that regard, I think this case may end up being more significant than Terri Schiavo's.
Exactly why I am trying to help out the fight, should the facts check out.
