See the problem?

Error: catch at test.d(3) hides catch at test.d(4)
The compiler does not reorder the exceptions because it
enforces order in the written code. As you say the compiler
knows the relationship, the one reading it may not.
So long as it errors from the hiding (as it appears it does) then
it's fine, and the previous example shown was wrong.
try {}
catch (Exception e) {} // most throwable objects derive from
Exception
catch (SpecialException e) {} // never used, because
Exception matches it all
