I understand it is all connected, but for the bottom to flex while connected to two endpoints, there has to be the gap or cutout. So yeah, not rocket science. And being an engineer, no matter who you work for, doesn’t mean your word is law when evaluating a description or picture of a design. Anybody who has spent any time doing npd knows that it is par for the course to hypothesize, prototype, and test and that often you are proven wrong, which is the point.
