No, that's not what Djokovic said. He has a history of breathing problem. With the injury timeout, he had the chance to continue to play, won the match and provided a very good 2nd round match for viewers.
I don't have problem with injury timeout between sets. If it's used as a tactic, than shame on the other player who lost his/her focus, concentration or whatever and played worse afterward. Players, who are smart enough, change tactics during match if they're down. Sometimes the tactics work, sometimes don't.
