I don't recall....
I don't recall reading any Airbus document suggesting positioning the aircraft any certain way after an RTO due to fire. I may be wrong, as I many times am, however.
Having said that, it is in our OPS manual to do so....if possible...to use the wind to blow the fire, smoke, flames, etc., away from the fuselage.
Airbus does mention in the RTO section of FCOM 3 that, if at all possible, when an evacuation is probable, we are to stay on the runway. Do not attempt to exit the runway onto a taxiway. Reasoning is mentioned in
above posts.
