Are you sure it's a cable and not a rigid rod/pipe that braces the flue?

I can't see from this far away.* Are you suggesting it can take a force
in more than one direction?* Even if it can, it would only be push and
pull, not sideways.

Maybe there is a second solid brace you can't see. That would
make a triangle.
Those are pretty solid.
