Religious buildings

[GoreBush]

Is it bug or intended that religious buildings from follower beliefs retain their buffs while corresponding religion gone?
Find myself doing weird gameplay things like constantly reshuffling my civ religious landscape attempting to build all this juicy mandirs, cathedrals, orders etc. It is a bit strange, can be unbalanced many ways, simply random and out of player control i think.

No bug, that is a viable strategy, it does however require a lot of faith to swap around between religions.
You probably need a good faith pump to pull it off, like orders, playing aztecs or similar.
