It doesn't really matter. It's just the idea of Susanoo used as a medium for regular techniques, which was expanded in anime. But yeah, I realise that Phoenix Sage Fire would be more fitting, but rather as a symbolic choice, since a lot of scenes reflect the moments from the 1-st VoTE fight, and this one (whatever Susanoo fire technique > Kirin) can be compared to Phoenix Sage Fire/Chidori combo Sasuke used in their first battle (when he decided to make a diversion with fire to land a Chidori on Naruto without missing).
