nole won the match emma so any weakness he showed in serving it out is immaterial.
the point I am making is that Fed had his final chance in the breaker: they both start from point zero in that breaker. nole played solid while fed crumbled in the clutch in that breaker. given the way Fed had been serving and the fact that he had won their last 3 set match (in Dubai), one had to believe that they both would have a chance to win it.
anybody can win once in a breaker.
