I think it works the way I described it, but somehow the whole mission is bugged. I keep having weeper Campbell spawning at the refinery even if I killed him in the second mission (or perhaps it has something to do with me not waiting for his death scene before moving to the backyard). However, in a playthouggh where that bug did not happen, I poisoned the still and did not complete any of Slackjaw's side objectives and the confrontation never happened.

EDIT: I believe the purpose of this confrontation (or what the developers wanted to tell) was that it was the result of Corvo stirring it up, acting for one side then the other, and that it was forcing you to choose one once and for all. So poisoning the still then helping Slackjaw discovering the identity of his enemy would be the logical way to play that confrontation, which also gives meaning to the achievements Street Conspiracy.
