Why do we need these two different code paths? Why not always return self._data in this case?

I saw this in Coordinate.copy() so I thought there might have some wrapper data to copy in PandasIndexAdapter but I admit I didn't checked it.
Indeed, now that I see why we have this in Coordinate.copy() I don't see any reason to have these two different code paths here.
