A320 Lateral Control NORMAL LAW

Hello,
Could someone please explain the lateral control under normal law which assist the pilot during decrab, as per the FCOM DSC 27-20-10-30(Lateral Control) it states "During Decarb phase, the aircraft will limit induced roll after pedal input, in order to ease flight crew control"
Say, I have a strong crosswind from the right on approach till ground level. As I decrab (Left rudder) will the FCTL SYSTEM :
(1) Immediately command spoiler extension on the right wing to prevent the induced roll ?
(2) As per the wording i.e. "after pedal input" Does it mean at the instance of the application of the opposite ruder? even before the YAW-COUPLING is sensed?
(3) Say the FCTL LAW deploys the Spoilers on the right wing to prevent induced roll to the LEFT (Right crosswind), and at the same time the crew demands a roll rate to the right to come back to the centerline, will the roll order be exacerbated or the crew roll rate demand will take precedence?

Thanks
