I'm off on a tangent unrelated to the book. "we" is computer programmers who deal with vectors and points. Mostly graphics, physics, games, etc.

So it’s not really correct to say that (x, y, 0) represents a vector, or that adding these projective coordinates is vector addition. Vector addition is represented by an identity matrix with the x, y coordinates in the rightmost column.
