Two possible answers:
1. They saw that Artificers are "arcane" but forgot they don't use ASF.
2. They thought Artificers would want to use Sorcerer scrolls for some reason, and then also thought it made sense for weapon-focused Artificers to be better at it.
I suppose that at least for people who enjoy Fire Shield scrolls there's some benefit to it... but in general, Artificers can ignore ASF almost completely.
