Rengar's bonetooth necklace quotes being played but not for every trophy

Uhm, That's akward.

TL;DR ever since the assassin update the bonetooth quotes got removed, but now when I play I will sometimes get 2-3 of them (like on stacks 1, 3, 4 ) but then I won't get them for 2 and 5.

Is this intended? I really want to hear "WHAT A GLORIOUS HUNT" at 5 stacks again.
