Even in high school in California when Lou developed a rep for flopping, anyone who really watched her play could not ever say she was not tough. As I stated before on this site, her flopping was purely a tactic to assure that refs would give her calls because she was often excessively mugged by opposing teams. People just assumed that her flopping was because she was weak.
As to announcers making mistakes and erroneous statements or calls about game events that is sort of thing is not really that unusual. I believe they often make those calls with out checking out replays. I have often seen cases where they maintain their positions even when a replay makes it obvious they were mistaken. So either they do not always watch the replays we see, or they just ignore the obvious to avoid losing face.
