I don't really understand this. That is the example above simply moves a 
dynamic such that it doesn't 'hang down' as lower as it did before.

Sure this in and of itself will help reduce the spacing?

This example is stating that #'extra-offset affects vertical spacing but 
simply by using this 'tweak' you are moving an 'object' such that it no 
longer hangs down as much and so take less overall vertical space.

So then making the #'outside-staff-priority = ##f while technically a 
valid point, is (probably) not necessary - at least just for this 
Notation Reference illustration.

Or did I miss something?

I cannot answer that, sorry.
