why sample t0 linearly from 0 to 1 in order to get a linear sampling in disparity

[shuochen365]

I can understand the paper moving the camera position origin to the z = -n plane.

t = -(near + rays_o[..., 2]) / rays_d[..., 2]

rays_o = rays_o + t[..., None] * rays_d

But I don't understand why t0 changes linearly from 0 to 1 in NDC space. Because according to the formula, it should be - 1 to 1.
