Leading by example is not necessarily the same as being a lead developer. For example, my principal engineer is easily a 10x'er as just a pure developer, but he's also a force multiplier for everybody on the team, he's literally a machine. He leads no one, I made him principal engineer so he didn't have to. If he was to just write code he'd be a 10x'er, with the other work he does to help his colleagues, he's many times more than that.
