Error in whackamole tutorial - section 2

Theres an error in the whackamole tutorial proveded with the installer, in the second pdf, Respawning the Mole,
in code sample 2.6 at the bottom, the pdf has:

function mole::onAnimationEnd(%this)
{
if( %this.getAnimationName() [b]!$=[/b] ("[b]animMoleComeOut[/b]" @ %this.moleColor) )
{
// after deleting the old mole schedule a respawn
// >%this.sceneGraph< is the level
%this.sceneGraph.schedule( 1500, "spawnMole");
%this.safeDelete();
}
}
Code Sample 2.6

In the code listing .txt it has

function mole::onAnimationEnd(%this)
{
   if( %this.getAnimationName() [b]$=[/b] ("[b]animMoleWhacked[/b]" @ %this.moleColor) )
   {
      // after deleting the old mole schedule a respawn
      // >%this.sceneGraph< is the level
      %this.sceneGraph.schedule( 1500, "spawnMole");
      %this.safeDelete();
   }
}

in the if statement it has !$= rather then the $=

also, the pdf one checks if the animation is called animMoleComeOut, whereas the txt checks if it is animMoleWhacked.

(and then on top of that I made a typo where I typed spwan instead of spawned, but those two variances provide a little bit of nussiance as well...


EDIT: well after fixing my typo, it appears both methods work, I'm wondering why 2 different versions were included though.
