I think that mirroring is something that we do not need to worry about. With mirroring, if there is the one interaction context in which the user interacts, then the mirroring merely provides multiple representations of the visual representation of that interaction context.

This single interaction context has to meet WCAG. The act of mirroring the visual display parts of that IC should not in any way affect whether or not it meets WCAG (which is our concern).

Best regards

Wow, I didn't consider multiple displays and I really don't think that is considered by the initial WCAG SC either.  It's a tough one however.  Focus would be in both renderings so they would be considered the same UI context to me.

If you have the same content open in two windows, ideally you should see a title difference, e.g. (1) (2) somewhere in the title.  I would think this should be considered separate UI contexts as I don't think I can figure out how focus would be in both simultaneously.  On the other hand I could see something where comparisons are taking place where focus change in one window effects the other window which may have no title, or same title as they are probably something like two views of the same thing showing differences, or other comparative analysis.  Still seems like focus drives ui-context, e.g. if you don't have focus your context should be restricted to the "window" where you do.

if they are truly identical in all respects then I don't think they would need to have different titles because it really doesn't matter which one you find - the are in fact the same thing. For example mirroring the display on your laptop, you don't require that everything be labeled a different label on the mirror.   The information exists in two places but you don't care which one is which since they are identical.

 However if they can be acted upon independently, for example you can scroll them to different positions, or you can do other things different on the two, and they are not an exact mirror, then I think they would need to have two different titles and this is in fact what I've seen most programs do.
