Well every jutsu have weakness and you can't help it, Well while you are in Mid air and moving too fast maybe you can't controll this technique also this technique can't do much damange and i think it can't damange person at all.
As itachi were lauched in the air he quickly starts to analyze situation and Starts perfoming jutsu by gathering Chakra, After he gathered enough he used Nature transformation to change this chakra Into wind chaka and make it as sharp as possible, After that he channels this sharp chakra into mouth and started releasing it into Air as it were released he quickly used Shape manipulation to change this Sharp chakra into Wind blast and Changed his flying location avoiding some attacks.
