I only know thumb = motion/current but now since you say, it's clear: people used x/y for 2D logically but the 2D plane used to be paper. which is parallel to the earth surface (usually). Computer screens are perpendicular so Y points up, not away from you.

So this makes sense with paper, TIL. With computers, Z traditionally means depth.
