Hmmm ... I'm using the words in a slightly different way.

You mean "the changes lists recorded in Subversion never overlap,
because we yank the file out of the old one while putting it into the
new one." That, plus the improved messaging it produces, is what I
meant by "help."

It's pretty typical of me to think about what the user wants, rather
than what the code happens to implement at any given time. What I
was talking about was "the list of changes the user wants to make or
has actually made, and believes to be associated into some sort of
collections he really would like Subversion to keep track of." These
lists might very well overlap (that is, the user might be involved in
more-or-less simultaneous tasks that unfortunately happen to touch
the same files); Subversion doesn't presently provide any assistance
in actually doing this thing, but the "help" I spoke of is "improved
alarm-bells if you stumble into this neighborhood." So when I talk
about "avoiding overlapping changelists," what I mean is "noticing
the alarms, stepping back from the keyboard, and rethinking your work-
