Mobs using Backstab ability from infront

Have noticed mobs that can cast backstab can do so from any angle, not just from behind.

Not sure if this is a code or DB issue.

how to reproduce:
Go and fight the level 8-9 murloc lurkers in Elwyn forest by logging camp.
stand face to face and see that they cast backstab while in front of you

I have confirmed that all mobs who can cast backstab do this.
