It does, but I think that's because the shading/colors used for the
circuit board are giving misleading cues as to which way it is
oriented.  Or something.  Even without the dialog, something doesn't
look quite right...

Given any more thought to just letting Blender do this grunt work? 
Could you export the board model in a format that Blender could swallow
up?  I don't think that would work for interactive development, but for
dog and pony shows...
