Nope. If you read the post, you'll see he mentions that it isn't related to uglification. It's a definition of unicode characters

To me the problem seems to be minification causing something to look like obfuscation. If you look at the article you can see that the minifier combined the short strings of hex characters into longer ones. I think it's entirely possible that the length of a string like that plays a factor in what gets flagged.

He does indeed mention that. However, as he is not Google, I'm not sure how he could possibly know that.
