The User Coordinate System is aligned to the
selected patch, which means z is aligned to
the patch normal, i.e. perpendicular to its
surface.
Since the UCS was re-aligned, but not moved it is still at its original origin. Zoom
out to see the rotation of the z-axis.
Each object defines an axis in a different way. Selecting e.g. a cylinder defines z
along its centerline.
An alternative way is using the command View | Coordinate System | Set

5.5 Set the Coordinate System's Origin at a Picked Point
Next move the origin to a selected point. This command is practically the same as 5.2 with just
one pick-point selected, but without the option to set an offset.
