Question about loadMovieNum and caching

say you have two buttons: the first button loads movie A.swf on level 2, the second button loads B.swf also on level 2. if i understand correctly, one movie will be kicked-out in the favor of the other because they’re on the same level right? now, let’s say both A.swf & B.swf have super simple preloaders that just have static text that say “loading” in frame 1:

if (_framesloaded>=_totalframes) {
	gotoAndPlay (2);
} else {
	gotoAndPlay (1);

my question is, whenever a movie is kicked-out, does it disappear from the cache as well? i ask because i don’t want their preloaders to keep appearing everytime the two movies switch between each other.
