multiple a new lows question

By mastermajora, in UFS Rules Q & A

a new low "R Commit: After your opponent fails to play a card from their hand as a form, play as a form from your hand at +1 difficulty." if i make your check fail then use a new low to play a attack would i use the second a new low before or after the attack resolves?.

wait till it resolves, then play the next a new low.

but the ability itself doesnt say to resolve, just to play it, so wouldnt you stack the responses and then start resolving the forms?

once the attack resolves, you got back to the opponent's turn, AND the window that they just failed a card. ANL again at this point
