Not really odd; I'd say it's more practical. After all, Himaruya probably wants the present timeline in the manga to concur with the events happening in reality.

If you think about it, Barack Obama's phrase has been repeated so many times in the media that just the mention of it turns the mind to the US. (Truth be told, "Yes We Can" seems overly optimistic but I guess it's appropriate for America's personality...)

And yes, it's probably more than a coincidence that America's voice was added at the same time as the 2008 Presidential Elections (Both Character CD and Volume 3 DVD came out in 2009, right?)
