STM32F105 Dual CAN Filters

On this processor both bxCAN cells share the filters located in CAN1. There is only a single CAN_FFA1R register whose bits are used to assign individual filters to FIFO 0 or FIFO 1. There is no bit allocating them to CAN1 or CAN2. Does this mean that when both CAN1 and CAN2 are active, they must have exactly the same filters?
