      Could you please explain the reasoning behind this?


It means that type_info equality can be determined by just comparing the
const char* pointers, instead of using strcmp to match equal names.

The pointer value will be unique, so will only compare equal to itself.

The Itanium ABI doesn't dictate the form of those strings.

When you call std::type_info::name() the '*' is not in the result. It's
just an implementation detail.
