Yes, but that's just how it works. A respected designer brings talent and years of experience, expertise, theoretical knowledge, and intuition to their task. But like most of us, they aren't very good at introspecting to explain the real reason they arrived at a particular design.

They are, nevertheless, required by business types to come up with some sort of justification, and that's what you just read. It doesn't matter whether it's truthful or accurate, so long as it's plausible from a business perspective.

Seems wildly successful to me considering we're all still talking about it despite the fact that they don't even use the logo any more.
