From my compiled Q&A : http://www.boardgamegeek.com/thread/1056508/unofficial-faq-c...
Q: When a dwarf ally is put into play by To Me! O My Kinsfolk! effect and he dies, does it get back under our deck from the discard pile?
A: The lasting effect created by To Me! O My Kinsfolk! only applies if the character is still in play at the end of the phase. After a card leaves play, it can no longer be targeted by effects unless those effects specifically target a card in an out of play state. The extra text on Sneak Attack was only to help players understand how it works, but it's the same for both cards.
We did reverse / reword some rulings that I had previously sent to players because either I was wrong or there was a better solution. If you want more clarification on particular rulings, you would have to remind me which ones I changed.
