Read the rest of the help on svn diff. As you said, the first use
case is all about the different ways you can diff versions of a single
path against itself.

  svn diff -r22:34 some/wc/path
  svn diff -r22:34 http://some/repos/path
  svn diff -r22 some/wc/path
  svn diff some/wc/path

This is the syntax that treats multiple paths as a list of independent
diff runs.

But the second use case mentioned in help allows you to diff two
arbitrary paths on the server, whether they be tags, branches, whatever:

  svn diff http://path/to/branch1 http://path/to/branch2
  svn diff http://path/to/branch1@51 http://path/to/branch2@78

Then we should file a bug. I'll try to reproduce.
