Torque 3D Beta 4,5: TerrainEditor duplicated code

As far I see this code contains something that never called:

void TerrainEditor::on3DMouseWheelDown( const Gui3DMouseEvent & event )
{
   if ( event.modifier & SI_CTRL && event.modifier & SI_SHIFT )
      setBrushPressure( mBrushPressure - 0.1f );

   else if ( event.modifier & SI_SHIFT )
      setBrushSoftness( mBrushSoftness + 0.05f );

   else if ( event.modifier & SI_CTRL )
   {
      Point2I newBrush = getBrushSize() - Point2I(1,1);  
      setBrushSize( newBrush.x, newBrush.y );
   }
   else if ( event.modifier & SI_SHIFT )
      setBrushSoftness( mBrushSoftness - 0.05f );
}

The last "else if()" part is not needed at all.
If we failed on first "if" check AND second, means there are no SI_SHIFT modifier, so the last check is just... copy-paste bug?
