I disagree, remember what happened If you broke one of the tenents then the Wraith of sithis hunted you down in your sleep and attacked, I imagine a similar occurrence would happen here, every night.
There's only such you can deal with, constantly staying half awake at the threat of being killed in your sleep, entually itd drive you into madness, or exhaustion would take hold and your fate sealed.
So, unless he has some ties remaining with the dark brotherhood and this being a special assignment or something, I can't agree with it.

But wouldn't that threat weaken by the waning of strength the DB? 

I mean if Sithis can't ensure the guild's survival, who's to say it can't track and torment one individual.
