I'm pretty sure that you roll again for Daze for the additional strikes/attack from Sweeping, Doublestrike, Triplestrike, and Battle Fury. The thing is that Daze says you roll during the declare attack step or, if that phase is skipped, as soon as the attack begins. I wish they would clean up the strike/attack terminology, which is ambiguous. Battle Fury is an entire extra attack action, with another attack sequence, so that's clear cut. The difference between the wording on Sweeping and Doublestrike/Triplestrike is a little puzzling, but it doesn't actually change the way they interact with Daze.
