Consider this:

     try {
         auto foo = Foo();
     } catch (FooCreationException) {
         // ...
     } else {
         foo.doSomethingWithFoo();
     }
     // foo does not exist here

versus this:

     Foo foo;
     try {
         foo = Foo();
     } catch (FooCreationException) {
         // ...
     } else {
         foo.doSomethingWithFoo();
     }
     // foo exists here - it could be initialized, it could be 
not...
