Why do elements mirrored across a centerline (annotation) not have automatic symmetry?

When I mirror elements across a regular line (draw group) they have a symmetric relation automatically. Why is it when I do this with a centerline (annotation group) there is no automatic symmetry applied?  You would think it would.  Thanks.

Hi there @CR1,

 

Because the centerline is, as you point out, an "annotation", and as such only gets momentary positioning reference, whereas if you use a sketch line, that physical geometry is then able to persistantly drive the mirror axis, giving the user automatic symmetry by the system.
