OOOhh!  You're right!  That's simply TERRIBLE!  I sure hope you didn't sprain 
a finger with all that typing!

Unnecessary feature and one of limited benefit.

As long as 'Type1' and 'Type2' are actual types, as your nomenclature hints, 
and not type parameters.  'ShortName' is not a typedef, though, it's a new type.

I think you'll just have to put up with typing Ctrl-V or letting your IDE 
autocomplete all those horrible, finger-spraining, documentation-improving, 
safety-guaranteeing, extremely low-overhead, helpfully redundant type 
declarataions.  Maybe you should wear a finger brace to relieve the strain.

Or spend a year tarring roofs to get a sense of perspective.
