That doesn't really seem to agree with Paul Buchheit's quote on the wikipedia entry regarding the topic, where he said he "wanted something that, once you put it in there, would be hard to take out," adding that the slogan was "also a bit of a jab at a lot of the other companies, especially our competitors, who at the time, in our opinion, were kind of exploiting the users to some extent." I'm pretty sure the plain meaning of the phrase was one of the intended senses, suggesting that any aggressively selfish behavior falls under its umbrella.
It would be a little opportunistic to, on the one hand, have the founders include the following line in a company manifesto: "Don’t be evil. We believe strongly that in the long term, we will be better served — as shareholders and in all other ways — by a company that does good things for the world even if we forgo some short term gains" and garner all the amazing PR that's come from that association over the years--but then turn around and claim, oh, no, that was really mostly just talking about user experience. And I doubt they'd make that claim.
I got out the book and checked, and actually you're right, it was a more general statement than just about UX. (It was meant to be a frank and memorable statement that applied across the board, from UX to the greater good.)
On the other hand, it was mostly an internal motto, and wasn't public until Eric Schmidt slipped it into an interview. It didn't become a public statement until it had already received a lot of press.
