It's not used ocassionally, it's used most of the time. You've pointed out some (small number of) examples of when it works.
Sadly, most of the time it leads to us having trouble on two counts. One, trouble moving the ball through the middle since we've made it so congested by pushing up. Two, trouble keeping the footywhen we do have it in the middle, because we look forward, have no one to kick it to, and turn it over.
Off the top of my head, some examples of the latter: I think Sylvia might have bombed a ball forward to no one fairly early in the game, while Morton definitely kicked the ball forward to no one when he was on the southern side of the ground in the last, and Martin did it with more style when he kicked towards the City end, etc. There were also plenty of times per game where we simply handballed it around or kicked sideways because there was no one to kick to up the ground.
