My understanding is that he was referring to impact on the company. At FANG, there is no single product where your impact has a significant impact on the company as a whole.
Sure you can go to AWS and work on Lambda. And then you can work on a feature of Lambda. It's very likely that the feature is going to have an extremely minimal impact on Amazon as a whole company.
I'd imagine the same is for apple. You can join, go work on a secret feature of a feature on the iPhone, launch it, and then yay. You've now contributed to a feature of a feature of a product with 100s or 1000s of other features.
