Object stats counted even if they are out of view, why?

Hi, I have a terrain with mountains. Now I have one object, let's say traffic sign that I use as a prefab and I place it all over terrain (total of 30 signs). Stats of one sign are 1 draw call, 100 tris, 100 verts. Usualy I have only 1-3 traffic signs in my view and I would expect 1 draw call, 2 or 3 batched, and tris and verts rised for coresponding amount. But I see that almost all signs (20+) are batched (draw call), and also tris and verts are raised for same amount of 20+ signs. So, it is also counting signs that are out of view. Why is this happening? I'm using Unity 4.6 free Version.
