Yeah i think when you request shallow clone, by default it only gets
one branch (see --single-branch, often 'master'). So when you specify
--shallow-exclude you essentially say 'give me master branch but
exclude everything from master'.
I should probably make it print a friendlier message than simply
terminateing like that (it's still a guess, I haven't tried it out)

You're saying 'give me master branch, exclude everything that is
reachable from stable/2.0.x'. If there's nothing in common between
master and this branch, you get full 'master' branch. Otherwise you
get a shallow 'master' branch.
This option is meant to give you another way to cut the history.
Instead of saying 'give me X latest commits' with --shallow, you could
say 'give me commits since this cut point' and the cut point is often
a tag, on the same branch. Using an unrelated bracnh or tag could give
some surprising result.
