It's not a ko threat.  Lazarus will attack a fairly small group inside
of territory that is controlled by the opponent.   The attack is easily
refuted with a capture, and when that happens no time was lost.   But
the opponent must capture immediately or the threat Lazarus made
actually works.    It's as if Lazarus just wants to see if a quick cheap
shot will work.  

Of course having it do this inside the tree, is a distraction.  It's
like a horizon effect in chess, a pointless check to kill 2 ply.
