I think that they've been patched, I haven't seen any Youtube videos of them after it. Yeah, I think that because that horse was there, the paranormal activity kicked up, in which Rockstar put a part in the program to cause the horse to go away, signaling the rise in paranormal activity. So, if you see any horses there (especially a one that looks black and kinda scraggly) then there probably will be some more paranormal activity in the area.
