I've dissected quite a few TV's in past years, and the deflection yoke has a rather complex winding pattern, where the windings are closer together at the neck, and spread outward around the funnel-area of the tube. If I recall, there are 4 coils at 90-degree intervals, and the top/bottom coils are series-connected for vertical deflection, whereas the side coils are series-connected for horizontal deflection. Lots of pictures online; notice how many styles there are.
