They were talking about the fact that the ball should have been moved but it was going to be moved BACKWARDS.
Periera said this week that he would have moved the ball but wasn't sure it would have been a 1st down. With that being a possibility, its impossible that they challenge only the 1st down part of it.
And the outcome does change. The ball is moved.
This is taken off wikipedia and I'm aware of the fallibility of wikis so you can spare me that and stubbornly reject it. But I know for a fact that this has been corroborated by more official sources.

If a play is overturned, the official is also responsible for making any related revisions to the game clock if applicable, especially in late, game-ending situation. For instance, if a player makes a reception and runs a long distance several seconds may run off the game clock. If the play is challenged and the catch overturned, the game clock would be reset to have stopped at the moment of incompletion (presumably adding time back to the clock).
Note that the spot of the ball may be challenged in certain cases. In such cases, a decision to respot football is not enough to win the challenge; Only when ball is respotted AND ruling on the field is reversed by remeasurement, the challenging team would not be charged their timeout.
Some unusual, and confusing sequences of events can occur during replay stoppages, and most have been address through rules clarifications. For instance, inside the two minute warning, if a team calls a timeout in the normal course of play, but the replay assistant calls for a challenge of that play, the initial timeout is ignored and restored in favor of the replay stoppage. Likewise, if a team commits a delay of game penalty (before the snap), the opposing team still has the opportunity to challenge, provided it is done before the ensuing snap.
The current replay system replaced a previous system used during from 1986 through 1992; procedure similar to that of college football was used. From prior to 1986, and from 1993-1998, there was no replay system utilized. While there is occasional controversy over the appropriateness of overturned calls, the system is generally accepted as an effective, and necessary way to ensure a fair game.
