Ne-Yo discovered Justin Bieber before Usher did - Huh?

This is a weird one. Ne-Yo has just claimed he discovered Justin at 11 when he came to a show and performed, 2 years before Usher met Justin. Isn't this weird if this is true?
Justin Bieber was first discovered by R&B singer Ne-Yo?

“Things happen for a reason,” says Ne-Yo who revealed that he was actually the “first” person to witness the talent of the hottest underage teen in the world today.
