No. apparentDecel takes effect as long as the truck is moving. Vehicles using the Krauss-model will keep a gap that allows safe braking in case the leader vehicle brakes with apparentDecel (even though the leader will in fact only brake with its 'decel' value). If apparentDecel is higher than decel, vehicles will keep a larger gap then they would otherwise. That gap increases depending on the speed of the truck. Only when the truck is standing, it's decel or apparent decel plays no role since it obvious cannot brake anymore.
