Yeah but this is the mistake the NFL has made. When the punter, QB or anyone else (as you said) kicks or bats the ball out, they have never thrown a flag! They should throw a flag if it is a penalty and then say it is declined and let the offense decide like they do with all other plays. If they don't throw a flag, then nobody knows it is a penalty.
Watching that game live, I don't think one person on the field knew that was a penalty. The real mistake by the NFL is not throwing a flag when the punter does it. That doesn't make any sense, they throw a flag whenever there is a penalty no matter what, why would they decide on a play with a safety to not throw the flag and just say penalty declined. The NFL set a bad precedent and caused the issue on this play. When you see people do it for years and not get a flagged thrown, even if it is in the rulebook it doesn't make sense to all of a sudden throw a flag. You know what I'm saying?
This is always called when a punter or QB bats/kicks a ball through their own end zone, but most times it's not acknowledged by the TV crew because it's an automatic decline by the defense and the safety is awarded. TV crews are too busy showing the celebration of the safety and replays of it to acknowledge a meaningless call, the confusing part was it was the defense doing the batting for a change in which the penalty would be accepted on this type of play. It was an easy call that was completely butchered by the crew, and sadly it's not reviewable by instant replay
