The 'oo' does seem to look quite a bit like an infinity symbol. And if I had to guess, I'd say it's intentional.

However, it's not as obvious what branding message it's supposed to convey. Unfortunately, my first thought was something like: "Don't count us out, we'll be around forever!" Which probably isn't a good message. Other visual effects, e.g. the negative space in the FedEx logo, are more obvious.

Then again, maybe no one noticed it. Or maybe it's just a sideways 8.
