Kindred gets 4 basic attacks off in one animation.
Slow the video down to 0.5, watch the pink ward pop at 35:54. Earlier in this video at 13:44, she pops a 400 HP Lee Sin with one attack. Something is fishy here.

EDIT: I'll concede to the Thresh pink ward placement argument. It seems legit. The Lee Sin kill at 13:44 is still odd to me though. Considering resistances, she'd have to deal upwards of 500 damage in a single instance.... at level 4.
