It's correct, although probably it seems strange at a first glance.

It dumps MBR and EBR tables, nothing else. It means that you can
see all the values as stored on the device without any calculation.

I agree that this info is not too useful. Maybe we can change this old
thing and describe the whole chain of the MBR->EBR->EBR... in more
readable and more precise way. Not sure, but I guess nobody cares
about this output backward compatibility.
