I don't know about the specifics of how this is related to their algorithm, but it makes perfect sense from a philosophical standpoint. You are using Google (the world's most well-known search engine) to search for other search engines. So either you are clueless about what a search engine is (in which case they win, since you're using them without knowing the term), or you're explicitly looking for alternatives (in which case, according to their philosophy, the way to serve you best is to give you a great list of all the other search engines out there).
