look at the zagged line on the left side sphere.Unfortunally for now you can use only first UVMap for normal map, in the future we will remove this limitation, now you can just use for normal map first UVMap. I made a little changes in your example, just made second UVMap as first, and used first UVMap for Normal Map.
it gives me the normal error base on the UVMap which is for AO Map.
UVMap is for AO and UVMap.001 is for normal map. I don't know but somehow UVMap affects to normal map that does not be connected to.
if you look at the right side one, it dosen't have that line
Blend4web and that kind of thing.
