Yes, it is unneccesary, but, well, it does no harm :)

In fact you may expect that each PCI device driver
can be used for a (near) arbitrary number of cards.
The reason for multiple device entries in the config
file is usually, that ISA cards need very specific 
attach addresses, and if you have multiple cards, then
each individual one has to be made known to the kernel.

PCI cards are auto-configured by the PCI BIOS, and the
drivers use whatever the PCI BIOS choose for the card's
registers and memory regions.
