The object is dynamically allocated exactly to allow it to survive
beyond the current scope if needed. The alternative to returning it
inside auto_ptr is to return a naked pointer but this is not
exception-safe.

As you said, you can always detach the underlying pointer from auto_ptr
(with the release() call) and store it anywhere you want (e.g., in
boost shared_ptr or as a member of a class). We use auto_ptr because
it is available as part of the standard C++ library and doesn't require
any external dependencies.
