Probably /dev/sdb1 and /dev/sda3 have the same labels and mount
simply mounts them in a consistent way according to some logic
we're not aware of.
I'd say: if it works don't touch it ;)
What remains unresolved is the question whether data=writeback is ok
or not. We'll see if somebody has more information on that one...
