Caesar worked for a long time with Vegapunk, who most likely is the foremost expert in Devil Fruit in the world, it would not be weird if he had learned that DF reincarnate in the closest fruit of the same time, so he left that bag of apples. He also has something to do with the SAD production, right? Oh, it could have reappered there, but only if there was a fruit of the same type.

I wonder about that, because somebody commented that it's due to a peculiarity of his body that he can eat more than one Devil Fruit without dying (the Cerberus theory is very intriguing), not the power of the Yomi Yomi no Mi. Or at least, I can remember clearly someone spoke of an anomaly, though it is also possible they simply meant the Yomi Yomi.
