That’s just how instancing works in blender. You put a geometry in the top socket and the geometry in the lower socket will be instanced on each of this geo’s points. For instance (hehe) if you had piped in a cube instead of a single point, you’d have 4 lines on each of its verts but the cube would disappear. To get them both to show you’d have to draw another noodle from the instancer object and add it to the instance on points node with a join geometry node afterwards.
