I think that because originally, the value of <tag> was required to be 
fully-qualified rule name.

Later, I was hacking on the 'make' and 'notfile' rules, and decided that 
__name__ is too obscure, so I fixed the internal mechanism that handles "@" 
values of features. That made full name unnecessary for all features, 
including <tag>.

I've just modified the testcase to use both full name and local name, and it 
works fine. I've committed this change.
