I'm not an electrician, but that is redundant and not really needed, right?

That is correct. The lower value fuse will fail first, the higher value fuse doesn't *do* anything. Setting up two fuses in series doesn't offer any more protection than a single fuse.
Using two fuses in parallel allows you to pull more current, much in the same way twinning a water line will give you more output at the end of the pipe. IMO, if you've got an accessory pulling 30A (two 15A fuses), and it isn't a clothes dryer or electric stove, you're doing something wrong.
