Let's back up a few steps here.

'''Rock Lee uses the Dancing Leaf Shadow on Sasuke. He's about to use the Primary Lotus, but is stopped by Ningame and Might Guy. Therefore, Sasuke doesn't see the Primary Lotus.'''

'''Rock Lee uses the Primary Lotus on Dosu Kinuta to protect Sakura and her team. Sasuke was unconscious at the time, so he didn't see Lee use the Primary Lotus.'''

'''Sasuke finishes the second stage of the chunin exams, and enters the preliminaries, in which he faces off against Yoroi Akado. Since Sasuke has already seen the Dancing Leaf Shadow, he's copied it. But, since he hasn't seen the Primary Lotus, he's created the Lion Barrage.'''

You can say what you will about the Sharingan, but everyone in the anime, manga, movies, databooks and novels all explicitly say that the Sharingan is a copier, regardless of your preference and/or opinion. And Kakashi was famed for being the Copy Ninja because no one else - Uchiha or not - has copied as many jutsus as he has.
