It's more like "two lines and/or surfaces (planes) intersect, and corner..." It's not complete. や shows it's not two lines and a plane intersecting, but two lines, two planes, (maybe a line and a plane?), etc. Maybe they're thinking that spheres or circles or cubes or other such things can intersect.
