SimSets and delete()

In experimenting with SimSets, I've discovered that apparently, if you delete an object, it is also automatically removed from any SimSets that it was stored in. Is this true? For instance:

echo("Initial count of SimSet: " @ %mySimSet.getCount());
			
%object = %mySimSet.getObject(1);
%object.delete();
			
echo("Latter count of SimSet: " @ %mySimSet.getCount());

Let's say initiall the SimSet mySimSet contains 3 objects. It will echo:

Initial count of SimSet: 3
Latter count of SimSet: 2

So apparently, even though I *never* issued a %mySimSet.remove(%object) command, it seems that Torque is smart enough to remove the object from the SimSet automatically. Even though this has been my experience thanks to experimentation, I just want to confirm on here that this is indeed the behavior. I assume this happens on *all* SimSets, so if a given object is part of many SimSets, when it is deleted, it will be removed from all of them?

Such automatic behavior is indeed nice, provided one knows about it and expects it. ;-)
