I watched the play live, and watched all the replays, but couldn't tell if one official threw two flags, or two officials each threw a single flag. There appeared to be two separate sequences of contact, and different wing officials (one deep, one short) having different views, reacting to different sequences of contact makes a lot more sense.
At this level, it would be difficult to believe any single official would throw two flags to represent mutual contacts between receiver and defender. It's much more likely either a single flag would be directed at the more severe interference, or absent a really clear "more severe contact", the interaction between players would be considered mutual and ignored (at other levels, possibly followed by some instructive cautioning).
The wing official who bore the brunt of the Atlanta Coaches tirade, showed great poise in totally ignoring all the childish posturing and screaming. At some levels, that level, and length, of behavior would, and should, draw it's own flag.
