set_coordinate_selection and multidimensional arrays

[hinxx]

This is from tutorial:

z = zarr.array(np.arange(15).reshape(3, 5))
z[:]
array([[ 0,  1,  2,  3,  4],
       [ 5,  6,  7,  8,  9],
       [10, 11, 12, 13, 14]])
z.get_coordinate_selection(([0, 2], [1, 3]))
array([ 1, 13])

I can not "see" how the result is array([ 1, 13]) and not array([ 2, 8]) 😮‍💨 .
Can someone explain this, please?

I think I see it now: 1 comes from coordinate 0,1 (first elements of two lists), and 13 comes from coordinate 2,3 (second elements of two lists).
