Using python 2.7.10, xarray 0.7.2

python arr = xarray.DataArray(numpy.empty((3,3)), coords={'a':['a1', 'a2', 'a3'], 'b':['b1', 'b2', 'b3']}, dims=['a', 'b']) arr.loc['a2':'a3'] = arr.loc['a1':'a2']*arr.loc['a1'] arr.loc['a2':'a3'] = arr.loc['a1']*arr.loc['a1':'a2']

First assignment statements succeeds, while the second one generates ValueError: could not broadcast input array from shape (3,2) into shape (2,3)

I'd expect the multiplication not to swap the order of dimensions. But if it does, the assignment should be able to swap it back.
