Are you referring to the representation of parallel-woundedness? The spiral wound tubes have spirals seams shown. You can't show the seams like that on a parallel wound tube, so the artist drew what looks like a circumferential line on the tube. Symbolism. It's like, oh yeah.... I "get it."
Nothing wrong here.
