There is no question that this is the case and that the current behavior
is right. The question I am raising is whether there are scenarios where
the current behavior could still be refined to make the experience better.
 If I checkout repository at r100, so my entire working copy is at r100.
If I then do a commit of some files and the new revision comes back as
r101. Then just as an example, in this scenario Subversion could
theoretically update the folders in the working copy to r101. If I had
committed r102, then it couldn't safely do this and would not try to.

There might be better ways to do this, it was just an idea. It does not
remove the issue altogether but it could make the user experience better
for a some scenarios.

One thing is clear, in a standard multiple developer scenario with a
variety of commits happening from multiple sources, then the current
behavior is correct and probably cannot really be improved much. I am not
suggesting that Subversion is broken or took a short cut.
