> the two groups of words are linearly separable

This is missing the point. What we have is two dimensions* of hundreds, but those two dimensions chosen show that the vector between a masculine word and its feminine counterpart is very nearly constant, at least across these words and excluding other dimensions.

What you're saying, a line/plane/hyper-plane that separates a dimension of gender into male and female, might also exist. But since gender neutral terms also exist, we would expect that to be a plane at which gender neutral terms have a 50/50% chance of falling to either side of the plane, and ideally nearby.

* Possibly a pseudo dimension that's a composite of multiple dimensions; IDK, I didn't read the paper.

Just needs to be a separating manifold if we use the kernel trick ;)
