if it's useful internally, then I can't think of a better form of branding than tidying up the formatting, slapping a logo on the bottom and knowing that it's going to be downloaded and referred to by the people most likely to require your specialised services. For that matter I was planning on tidying up and releasing the ones I created for myself to learn the framework at some point, and I have no desire whatsoever to sell my services as a programmer (nor should any sane person want to hire me).
I have to wonder what the motivation for releasing it as a 10MB(!) pdf was though.
You know the sort. I'm currently de-flashing a website where google can only see the <title> tag. Everything else is an image or a flash, and even the flash when torn apart is mostly pictures of text and individually placed characters… but it remains true to the designer's vision. A pity no one ever sees it because it is unsearchable.
(It also would have been nice if the flash artiste had delivered the source files, but then I suppose he was afraid someone would sully his masterpiece.)
Is it simply the name brand promotion that it generates?
