You are correct, but bear in mind that I provided only a very few words of summary for a rather detailed, patient analysis and set of conclusions in the original work.  Before judging their conclusions you might want to be sure that you understand their point more directly than by hearsay from a very cursory precis.

As best I understand the book it is their conclusion that even the second case requires a person to understand the entire app.  This apparent paradox is resolved by understanding that the overview knowledge, while detailed, isn't necessarily atomic.  It's a matter of someone exercising a form of leadership to assure consistency and a certain focus in a project.  By analogy, the chief executive of a nation need not understand necessarily every single detail of every action occurring in every corner of their realm, but the should have a keen grasp of the nation as a whole and a vision for its direction.  This is the sort of "understand the project" that I infer and remember from the book.

I conclude that a project that grows beyond such a vision needs to have fractal subprojects that fit within such scope and operate with some autonomy.

This is a direction that might address the valid point you raised.  I recommend the book not so much to endorse its conclusions as to commend its even-handed and comprehensive analysis and the segregation thereof from the authors' agenda or theories.  While it draws conclusions in the latter part of the book, it does not go so far as to recommend anything.  They have no pet buzzword or system to promote, only observations as to what works and fails under different methodological structures.  It's a foundational work.

As to how "useful" their conclusions are, I'll let you judge for yourself after you've bypassed the filter of my reporting.  I'd be surprised if you maintained your dyspeptic view after that.
