Actually I have doubts about it myself (I did not write it myself), but it is after all the first encounter of proper cataphracts by the Romans, so it had to have an impact. I was more under the relation that Partho-Sassanian conflicts against Rome would have been more decisive to the creation of a Roman cataphractarius and as hinted from Roman sources, these cataphracts were specifically mentioned "Clibanarii", a term that has caused much needless confusion. That's my take on the whole issue, though.
