I agree with this, that's exactly how I would have answered.

A widget can get extra space without having expand=true, say for
example it's in a container that forces all children to be the same
size.

expand means "extra space is useful" while align describes how to
handle the extra space.

If you think of an image widget, maybe centering the image and scaling
the image up to fill the space would both be useful behaviors,
depending on the app. So you could use align=CENTER or align=FILL.
Something like that.
