Gamepiece Cycle

[Flimsor]

I've been looking through the manual, and I'm still missing a couple of parts about how balls are reintroduced and what happens to them after being scored. I understand that the general flow is:
1. The pedestal lights up once there are no balls already in play
2. The ball is retrieved from the pedestal
3. The ball is introduced into play from the side of the field
4. The ball is scored by a robot
From here, things get a little foggy. G39 specifies that team members must remain in contact with their alliance station or human player area. If balls are being scored onto the opposite side of the field of the pedestals, then how are the balls getting to the pedestals in the first place? Is that being done by the field crew, or is the human player given an exception to run across the field and retrieve the ball and put it on the pedestal? It's not too big of a deal, but I figured it was something that should have been covered.
