You can think of this phrase as putting a country into a family: one place is the mother, and someone or something else is her child. In the warm use, the child is a person — you came out of that country, you carry her language and her food, and the tie holds even after forty years away. In the cold use, the child is another country: an empire calls itself the mother and calls the land it rules a colony. Same picture, two very different reasons for using it, so the phrase can be full of love or full of power.
