Clone Differences?

So I opened a the new clone battle pack...and noticed the eyes on each of the figs was different. I'm not sure if this is just ridiculously poor printing, or if this is meant to give individuality to the clones as they have in the series. How old is this?

 

Edit: Apparently it doesn't animate, click "All Sizes" to see the differences. Excuse the photography, I just noticed it and wanted to throw up some pics. I'll take better ones later if anyone wants.
