Complex and seemingly pretentious design pitches are actually a good way to explain to a company the way a design or design metaphor might subconsciously impact or impress its users. There are two problems here though: 1) the pitch is inane, for the reasons pointed out in the linked post, and 2) even if the idea weren't dumb, spelling it out explicitly for the customer is a great way to ruin the magic. (Fedex doesn't tell everyone to look for the arrow in their logo, and Gmail's slogan isn't "The envelope is also an M for mail!") Good design is often subtle of even invisible, and not just logos.
