Double dropping Alien PQ?

I know of a group that got 8 items on 1x. (One of those was a chair)

How is that even possible? Not to be exceptic but that sounds like bs. Of all the people i know of that run in khaini, I've heard of them getting 1 drop at aran/evan (and this barely happens). 2 sounds far fetched but i guess i'd still believe it, but 8 items would mean 2 of the bosses dropped 3 items each... on 1x, i think they were pulling your leg.
