Hmmm. I was looking at it from a balancing point of view. Basically that once he is knocked unconscious, the aura/whatever that has tagged the target no longer has that connection with the user and simply goes inert/dissipates, thereby ending the effects of the semblance.

But it does bring up an interesting point; if Semblance is an active use of Aura (outside passive semblances such as Qrow's), does it still work if the user is no longer conscious for it to activate? Yang doesn't continue to get stronger after she's fallen unconscious as far as we are aware, but that's a hard one to judge. Weiss hasn't summoned anything in her sleep as far as we know, Pyrrha didn't appear to display any problems while she was sleeping and trying to come to terms with the Maidens thing or I'm sure it would have been brought up sometime, and Ruby has never shown any propensity to shed rose petals so far.

Personally I am inclined to say that active effects of semblances do stop when the user loses consciousness, unless the semblance is specifically geared around that.
