The way nextToken() is overriden, it first returns the token matched by the rule, and subsequently any additional queued token before matching a new token in the input stream. Lexer.emit(x) sets x as the token matched by the rule. That's why the token emitted with Lexer.emit(Token) is returned before any queued token(s).
