when you apply a bump map to an object, the value (intensity) of the map is
inverted on the opposite sides of the polygons you apply it to. – you can see
this real quick by applwing planar mapping coordinates to a sphere, and
applying a bump mapped material – the area on the opposite side of your object
will have the bump map inverted.
I'm guessing that when you mirror an object, the normals are getting flipped,
thus showing the inverted area of your bump mapping.
