John, Yes, that is the way it is supposed to work. The collection stores and uses whichever form it is given. This can work because the XY array is very similar to the [(x,y), (x,y)...] form; both are single objects, and they behave the same when one says, "for xy in XY:", or if one calls the array constructor with either as an argument.
