Madara ran the plan through his mind and understood Black Zetsu's scheme.
It sounded complicated, but it was actually quite simple.
After all, they had been doing the same thing before.
At first, Nagato had been the chosen one, with Obito serving as supervisor and assistant.
When Nagato betrayed them, the backup plan became Obito, with Black Zetsu serving as supervisor and assistant.
