I thought that was the intent of the bill: Get the case into federal court, where it would be heard from the beginning (de novo). That would (implied) put Terri's feeding tube back in while the whole lengthy process of testimony, witnesses, finding of fact, etc. began anew, giving her months if not years of reprieve. Unfortunately, while putting the sustenance supply back was strongly and blatantly implied, it was not explicitly stated. And so here we are.
In other words, what Congress did was entirely symbolic. That's a shock.
