I can say it because Zoro until this point used it only like a "double jump". Have you seen him using like Sanji, kicking the air multiple times in order to travel great distances? No, and he probably will never do it. Can Zoro travel from the library/school to west village using clear lance alone? I don't think so.
It can be used so Zoro can change the trajectory of his movement in air once, and that's it. Differently Sanji can stay in air indefinitely freely with 360 movements without a problem, something Zoro can't do. It's not that difficult.

Zoro was falling off the island. He used it to travel great distance to get back on the island. It's that simple. He's used it twice so it's not a fluke.
The manga makes it clear he can use it to travel through the air. The fact that he doesn't it just bad writing and makes Oda look bad.
