I assume the purpose of the Now Playing clearing after a while is the idea that when people start a "new session" with their device it should be "clean". Like, if Now Playing didn't randomly disappear then for most people it would always be on, indicating some paused music or podcast playback. It would also never give a chance for that elusive "start playing" experience that shows up in its place sometimes to recommend that I listen to one of four songs/podcast episodes.
