Like I said before, I think he was given the greenlight to return it. If he wasn't and told specifically, "Don't take it out of the EZ", then we will probably hear about it.
With the new kicking format, if the kick is into the EZ, that decision has to almost be "premeditated". It isn't like the days of old where a returner could see how things are breaking ahead of him. Since nobody could move, until it was in Nixon's hands, he was going no matter what I think. Guessing the other 10 Packer players were made aware of it as well.
Too bad it didn't work out, but had it, I think people would be talking about how smart of a dice roll it was.
