Things are as they should be. If you put enough new files in there, they
will get overwritten but unless the file system is about to take more space
for the directory than it did before, the file system doesn't erase the
memory that contains that entries that used to be there, if you know what I
mean.
Really, though catting a directory means nothing, nothing you see you try it
means anything. It's just a silly thing to do and it's causing needless
worry, so stop it. :-)
