You are mis-interpreting his response.

Of course an excerpt you make from OSM is always a derivative database. 
But at the same time it is also a database in its own right.

Else the whole ODbL could only ever deal with two levels - "oh dear, I 
can only make derivative databases from the original database, nowhere 
does ODbL say anything about derivative database from derivative 
databases! FAIL!!! this means I cannot cut out a city from the UK 
extract, I always have to cut out my city from the planet file, because 
there are no provisions for derived databases of derived databases..."

He wasn't; you just have to understand that this is no either-or situation.

It's really just the same with CC licenses; you can make a derived work 
from a CC-licensed thing, and then that is a derived work with regard to 
its "mother" work but it is a CC-licensed work in its own right with 
regard to anything that might again be derived from it!
