New Nya print or pure coincidence?

A couple of days ago, I got three Ninjago minifigs from the Build a Minifigure section of my local Lego store. One of them was the Blue Kimono Nya seen here on the left. I happened to find this particular head that looks very Nya-like that I ended up using for her. However, on reviews of the Build a Minifigure figures I have seen online, Nya uses her default head (seen on Storm Nya on right for comparison). Is this head supposed to be Nya's, or is it just a coincidence that it looks like her?...
