Feature control frame reporting always reports the worst end of the axis for a cylinder because that is how position is supposed to be reported. When the Ø symbol is shown in the feature control frame, it is a cylindrical tolerance zone. All points on the measured feature must sit within the tolerance zone with the reported value being the worst point along the axis. If you were to only report one end, you would be at risk of passing bad parts because you are not considering where the other end of the cylinder sits.
