Assault Fire - possible bug.

I just saw somthing strange in my last game.
A Wolfen crossbowman use offensive stance to shot a unit (so it made two ranged attack) then he charge my unit with assault fire and kill that unit. After that he got a strange next RAGED attack on another unit, something like a pursuit attack but ranged... well dunno if this is a bug or intended by the devs... anyone saw somthing similar?
