Ackies do the tail wiggle in many different situations, when they are excited, when they are showing dominance or submissive behavoiur towards a cage mate, or when they've entered a new environment. But, the tail wiggle seems to have nothing to do with caudal luring. Ackies are not sit and wait predators, they move around in search off prey, therefore caudal luring would be inaffective for them. Also, ackies prey mostly on small insects and lizards in the wild, most of which would be scared off by a large ackie tail squirming about.
