Could someone clarify how i spend defence tokens...

A ship fires at my ship at medium range - I have an evade, brace and re-direct. Rules say in spend defence token step i can spend one or more defence tokens. My opponent roles a hit and an accuracy - i have a redirect, brace and evade. He accuracies my redirect. I elect to use my evade to make him re-roll the hit. He re-rolls and gets 2 hits!! Can i now spend my brace to reduce the damage to 1? Or has the spend defence token step already finished?

Thanks

Your interpretation is correct. Rerolls from evade happen immediately, so you can wait to see the result before deciding whether to spend more tokens. It all happens during the Spend Defense Tokens step of the attack procedure.
