stm32 CAN filter FIFO assignment?

Hello,

1. When creating a CAN filter, what is a reasonable strategy for FIFO assignment? 

2. What happens when the same filter is assigned to both FIFOs?

I am modifying an existing code base and the previous author always assigns the same filter to both FIFOs. Does this mean if the FIFO is full it will automatically start using the other FIFO?

TIA
