Google Maps shows Bhadrachalam in AP

I was casually browsing on Google maps around Bhadrachalam and noticed it is shown in AP, taking Godavari as the default border I was comparing the maps from TG & AP Govts and the actual border seems more like the second image. Curios as to why to this happened. Google generally takes the borders etc from publicly & Govt documents. Could this be due to the border village changes - between Mandals and districts during the partition?
