I think in a way, that's right. Subversion needs to store admin info
in the .svn directory within your working copy directory. If you
don't have a working copy directory, but only have a file, it has no
place to put its .svn info. If you wanted multiple externals to go
into a single directory, current Subversion would probably get quite
confused, since each external would expect to get complete control of
the contents of the .svn directory.

Related: you cannot check out a file -- the smallest unit you can
check out from a repo is a directory. (You can still export a single
file, if you just want to see its contents, but you can't then make
changes and check them back in.)

This is the existing enhancement request to be able to check out a
single file:
