Strange short life variables section in BaseFactory

[Eversor]

Diving through the code of the factories i noticed this part of code that is not clear if something is actually done or not... lines 327:331 of BaseFactory seems to declare variables that are left out of scope rapidly afterwards...

var armatureDataCopy:ArmatureData = data.getArmatureData(animationName);
if(armatureDataCopy)
{
var skinDataCopy:SkinData = armatureDataCopy.getSkinData("");
}
