Why does their position make a difference to how they sound on tv?
Because halves are the ones who make decisions the most, direct the teams, follow the coaches gameplan and so on, more than other positions. As a result, they can often give better insight into what's happening tactically on the pitch. Off the top of my head, these are the halves commentating in Aus: Johns, Fittler, Lockyer, Wally Lewis, Peter Sterling, Brett Finch. This is generally because they can provide better analysis than the likes of a prop who has a role of just carrying the ball forward and tackling for 80 minutes.
