If he just used the Demolition Fist maybe we can somehow force ourselves to accept that he managed to tap to the Fire Dragon King, Igneel's, move set. But the thing now is he reused the supposedly 1 time thing which is the Dragon King mode, that's just contradiction of what Mashima said in the earlier chapter hence just bad writing.
