Yes, it's the same with the Samurai and Ninja in Paizo's books.
Although some may view it as not hitting the same issues, the fact that it separates culture so distinctly from the class and name, for some, speaks of whitewashing. It separates that culture and significance of the titles and words from what they mean and their origins.
Not all would share this view, and not all share this view. However, whitewashing in that regards is actually worse than what OA did in using it's title.
You can see people being offended on both sides of this argument. There is no winning.
Speaking about not separating culture from class and name - if I wanted to create a human Samurai PC, the image of the character I'd be evisioning would be that of an Asian, and I would scour the net looking for an image along those lines. Tom Cruise is not the image for me that comes to mind when someone says they're playing a human Samurai character. Even non-human characters would exhibit an Asian look.
