One might construe N's orientation as being fully "non-attached" ...or
not; perhaps he lacks interest in relative considerations. Being
external obserers, we don't know what the true situation is for sure.
It's analogous to a Turing machine test: either a computer or a real
person is answering questions behind some opaque substance which blocks
our vision of the speaker. We are required to guess whether the
speaker is a computer or a real person, based solely on the content of
the answers.
Short of magical knowledge or cheating, our decision must be based on
common sense considerations.
By analogy, consider the case of Nisagardatta Maharaj. Is his apparent
lack of interest in things relative evidence of some deeper, more
profound Realization than than possessed by MMY? I think not.
Simply because MMY expresses more interest in things relative than N,
such as accumulating wealth, establishing Heaven on Earth, etc; this
cannot (IMO) be constued as evidence that MMY's realization falls short
of N's.
