Preloading question

look at this:

loadedbytes = _root.getBytesLoaded();
totalbytes = _root.getBytesTotal();
if (loadedbytes == totalbytes){
nextFrame();
}

alright, now, lets say on the next frame i have a layout with multiple external swfs… it’s my assumption that the code above will only load text/images and whatever else that’s in that particular swf, and the external one’s don’t get loaded from that right? i just want to be sure… thanks.
