Google AI Overviews and AI Mode, ChatGPT search, Perplexity and Microsoft Copilot all behave this way. The term is descriptive; it names a behavior these systems share.
For businesses, the practical difference is that inclusion is a citation decision made about page content, not only a ranking decision made about pages.
