That's interesting, I thought it was a direct (joke) response to the "Go" vs "Go!" situation. The "Go!" author stated that his language came first and then we find these conveniently aged commits the following day.
Either way, it's nice to see Google not taking itself too seriously.
I could be completely wrong of course, and the timing is convenient. I guess it depends on when these changes were pushed in, but then it's hard to tell when a possibly fake timestamp was made...
