The Telegraph:
He was the last of a generation that in youth was steadfast in its duty in the face of cruel sacrifice and we give thanks for his life - as well as those of his comrades - for upholding the same values and freedom that we continue to cherish and fight for today.

Harry Patch himself:
War isn't worth one life.

So no I don't think he was upholding the Telegraph's values or saying (as the Telegraph was expecting us to infer) that killing people in Iraq and Afghanistan was any more worthwhile than the war he was part of.
