This is probably a really obvious question . . . When triggered by the "battery empty" signal, does the charger always go into bulk? Or does it only go into bulk if the battery voltage is x Volts below the float voltage? (Can't remember what value x is, but I did read it somewhere in this forum)
Most Victron charge algorithms will start in bulk, then if the Volts are high quickly cycle through absorption to float. As you say, some will check the voltage of the battery. The 2 signal BMS has 2 functions - one is to turn the charger off or to float mode when the battery is full, the other is to turn the inverter OFF when the battery is empty. The inverter voltage settings would normally trigger the gen relay (if configured) to start the gen and to transfer the inverter into charge mode when the AC in is stable and synchronised. In this case, the voltage would be well down, and bulk mode would be initiated.
