It's pretty much as Omni-senpai says. The Sharingan can analyze/decipher/comprehend any technique and memorize it, but the user needs to be able to perform said technique. So it doesn't work like this: It's:
 * Sharingan user sees a Wind Release technique
 * analyzes what it is and how it works
 * memorizes it
 * can use it
 * Sharingan user sees a Wind Release technique
 * analyzes what it is and how it works
 * memorizes it
 * has to be able to use Wind Release nature transformation
 * if the above is true, then he can use said technique
