Because a Monk or a Carpenter has no GP gear, they cannot get more than that 400. So you only have that 400 when you go from a crafting/combat to a gathering.
N.B.: I was out hunting Ornery Karakuls between timed-node spawns the other day as a WHM, with iLvL 200 WHM mainhand, hat, and body, but wearing full right-hand side gathering gear, gathering belt, gathering legs, and gathering feet. Not only did I get a nice fleece yield (while one-shotting the poor wee sheepsies) , I had 600+ GP when I switched back to Miner.
