During an attack, unless otherwise specified, dice modification happens in very specific steps. The Phases page lists these, but the simple way to see it is:

Attacker rolls attack dice

Defender modifies attack dice

Attacker modifies attack dice

Defender rolls defense dice

Attacker modifies defense dice

Defender modifies defense dice

So whoever rolled the dice is the last to modify them. R4-B11 modifies defense dice of the opponent, so it happens during the Attacker Modifies Defense Dice step, before the defender can modify them. This is bad for the defender, since any dice you reroll cannot be rerolled again.

I hope that helps!
