I just read the manual for my Charles charger and here is what it reads:

When properly installed and connected, the C-Charger will automatically charge and maintain the batteries. When power is applied, the C-Charger will enter a bulk or “constant current” mode, during which a higher rate of charge is achieved to fully replenish the batteries. When the batteries near a full charge, the output current will decrease and the charger will enter a timed absorption mode. After four hours in absorption mode, the output will drop to a float rate to maintain the batteries at a temperature compensated finishing voltage (13.65 VDC @ 25_C for lead acid). 


It never states that the charger will return to a bulk charge unless it is power cycled, not sure if that is how it works or not but I know mine does similar to what you state. When i get to the boat, I cycle my breaker so the charger enters bulk rate. I will keep an eye on it more closely just to confirm the operation of the charger.
