The problem with that is the broadcast delays; live betting will always be as fast as possible (so that people who are physically at the match don't get much of a window to place a "guaranteed winner" bet, e.g. "next player to score"), but the various broadcast methods can add up to maybe 20 seconds' delay and most people probably wouldn't want the betting overlay to tell them that someone had scored before the TV pictures show them the action.
