Parasoul gaining multiple Precision stacks if use Taunt in quick succession, bug or intetional?

[Tsukiakari]

My friend and I found out that if you use Egret Call (Taunt to get precision) and any Special Moves in quick succession (Egret Call ->Nalpham Shot/Erget Dive/etc), you will get another 2 stacks of Precision (or getting the stacks base on your move's level I think). So is this a bug, or intentional?
