If that were true, shouldn't it be:
assert_equal expected , hash

I think it is probably a mistake, and they meant to try and show that you
can't do either of these, because it looks like you are passing a block.
assert_equal { :one => "eins", :two => "dos" } , hash
assert { :one => "eins", :two => "dos" } == hash
