Good point. Yes, that should be correct.

What this translates to: the .svn files determine what Subversion
believes to be the checked-out files. If the files in the regular
directories don't match that, they will appear to be modified files.
If that wasn't actually the case, i.e., they were really unmodified
but you got the revision wrong, then you now have a mess.

So in the sense of "Subversion isn't confused" your working directory
is valid; in the sense of "is the user confused" you may well have a
problem Again, the easy way to avoid this is to create working
directories with the normal mechanism, not to attempt to construct
them out of bits that you hope go together as you intended.
