No, Adam Savage has said something to this effect every time he talks about how his shop is organized and why it shifts around over time. The gist of it is that while most of his tools and common materials are first order retrievable, but theres a whole world of stuff in the shop that can't, so he thinks about where it should be stored and puts it there or there are times when a particular tool or set of tools is always used with some other thing in the shop, so it lives next to that other thing rather than on some rack of the same tools. What is most likely happening is that its all been in videos of which no readily searchable transcript exists, and he is not always very concise about explaining his core practices, so finding the exact quote is non-trivial.
