Isn't that what the internal filter is for?

No it is simply the final filter that determines what can get to the
injectors. It is not big enough to do all the filtering you might need
and has virtually no water separation ability.

So the internal filter isn't a filter?

Have you ever heard of "belt and suspenders"?

If one's good, more's better.
