Can overflow fire impulse deal additional damage because of the weakness brought by the aura?

[Deus Ciplin]

Kineticist can get the fire aura junction at lv.5, which gives the enemies in the kinetic aura weakness to fire.

It is written that "When you use an impulse that has the overflow trait, your kinetic aura deactivates until you revitalize it."

What's the meaning of "when"? Does the aura deactivate before the impulse deals damage so the target has no weakness, or after that so the target takes more damage?

I think the impulse has to complete and all effects resolve before you can say it was fully used. I've seen this question come up multiple times on discords, reddit, and here, and that has been the universal conclusion.

That's the conclusion based on it being tbtbt otherwise, also a pretty feelsbad moment if all of your overflows wouldn't benefit from the actual junction of the element.

I wonder how the fire impulses are gonna stack up to each other for damage considering overflow and stances like thermal nimbus. Flying flame might just output more since you can keep your passive damage up. The larger overflow aoe's will probably only be worth it with a significant amount of targets that you couldn't otherwise hit with flying flame.
