I thought so too at first, but no, you're wrong :-)
2.1-43 would also satisfy pkg (<< 3.0~), which is not intended. For that
matter, 2.0.1-1 would also satisfy that. Instead, you want to have
something that sorts before that 1. That is the ~. So, the 2.0.~ is
correct.
(Regarding the << rather than the <=, you're right of course)
