they are identical drives?  take a look at how you have them cabled.
/dev/sda would be the master and /dev/sdb would be the slave.

the only time i can think of that this might change would be if the
master (currently /dev/sda) failed completely and when you booted the
computer it was completely unrecognizable to the BIOS/linux.  at that
point because there would be only one /dev/sd* device detected your
slave might move to /dev/sda from /dev/sdb.
