The fact that both xmldecl and doctypedecl were optional and had the comment and pi tokens after them with a star, a failure to reach the end of the file to get the $ to match, will shuffle match attempts between the first and second line ... One first step in making the parser fail faster when encountering an invalid document.
Better from a performance standpoint because of less opportunities to backtrack, but also prevents comments from including their stopper and other stuff up until another comment or pi stopper is seen.
