How about simultaneous capacity (and preparedness)? The player need to stay in the presence. He needs to focus all energy on the shot before him. Once the caddie has left the player to hit the selected shot the caddie can do noting but think ahead. So everything that does not relate to the present is the caddies business.

One hand close to the putter. If the green is hit he should hand the putter to the player within 2 seconds, then get the divot, clean & put back the 6-iron. Get the bag. If he or the player needs a rest room he need to plan for that. Get the yardage book. Start studying the notes on the way to the green. Catch up with the player. Prepared to provide any information the player needs or discuss any topic. Do we have enough water? Do we have enough balls? Is the scorecard updated? Is it time to put on and/or prepare rain gear? Will we use a new ball on next tee?

Once the player has started putting on his own: Start thinking about the next tee. Check for wind indications.

Just guessing.... A combination of simultaneous capacity, look-ahead and preparedness.
