I understand your subjective reasoning behind the two differences and I happen to agree with you. I think the confusion boils down to:
In that case the answers were that the will of the subject was not to be maintained in a vegetative state and that she really was dead already.
THere is obviously no application of tentativity with regards to both procedural issues such as "will of the subject" or technical issues such as "really was dead already".
I can only concieve of two ways you can properly argue against this. One would be to point out the tentativity that I am not seeing. The other would be to explain the disparity.
I feel that holmes might be putting you off by seemingly calling you a hypocrite. I hope I am not doing the same.
