Sure you might be able to understand something given enough time and guidance. But to me a super programmer is someone who is able to make that leap and create something novel, useful, and valuable. For example, John Carmack, who many would describe as a super programmer, showed the rest of the game industry what could be done with 2.5D in Doom, and later commodity 3D hardware with Quake. You can certainly review his code since it's open source and understand it, but how many people could have independently done what he did when he did it? Not many I would wager.
