Why set origin and spacing with a reverse order? #7

In futils.util.py I found that the save_itk function use reversed origin and spacing as the parameters to save itk files. Could anyone gives some explanation? Why donot use the normal order???

%%

def save_itk(filename,scan,origin,spacing,dtype = 'uint8'):

    stk = sitk.GetImageFromArray(scan.astype(dtype))
    stk.SetOrigin(origin[::-1])
    stk.SetSpacing(spacing[::-1])

    writer = sitk.ImageFileWriter()
    writer.Execute(stk,filename,True)

%%

I think it was to save time in visualization. I used Slicer at the time.
