Anyone who knows what they're doing would describe it as a probabilistic model, which necessarily includes likelihoods and confidence bounds with probabilities other than 0 or 1. There is a certain probability that it is a part of one distribution, and an inverse probability that it is part of another distribution. Statisticians worth their salt will not state certainties as you seem to demand.

Hmm, I'm not sure where I demanded a certainty?

The phrasing implies mutual exclusivity here, which thus implies probability one of a data point belonging to one set and probability zero of that point belonging to the other set.

To be fair, in natural language it tends to be difficult to unambiguously represent ambiguity.

I wasn't drawing a dichotomy between "an outlier and a point that is far out of the distribution of the other points because of unmodeled variation". I was suggesting that they may be the same thing.
