In this fanfic, it could be that the connection between Harry and Godric's sword is enhanced. The sword, being a powerful magical object, might have been imbued with new powers or properties. Dementors are usually fought off with Patronuses, but here perhaps the sword can disrupt their essence. Since Harry is the one wielding it, his own courage and magic might combine with the sword's power to harm the dementors.
Well, in the fanfic world, the author might have given Harry the ability to use Godric's sword against dementors. Maybe the sword has some special enchantment in this story that makes it effective against the soul - sucking dementors.
In the fanfic, the idea that Harry kills a dementor with Godric's sword could be a creative twist on the existing magic rules. It might be that the sword has a unique ability to sever the connection between the dementor and the dark magic that sustains it. Harry, having a strong will and a connection to the sword through his Gryffindor heritage, is able to utilize this power to defeat the dementor. This departure from the traditional way of dealing with dementors adds an interesting element to the fanfic.
