This seems to be quite different to my interpretation, and it would be good to have some clarification, as the definition is quite fundamental to a number of use cases of OSM data.
You can always make an excerpt from an ODbL licensed database, which will then be an ODbL licensed database in its own right. That's the classic "derived database" thing.
While you have to retain attribution saying you derived this from X, in every other aspect your new, derived database stands on its own feet, and the ODbL applies to it in exactly the same fashion as it did to the "original" database.
Therefore, whenever the ODbL says "this database", that could either be the full OSM database; or you could make an excerpt from OSM, licensed under ODbL, which would then again be "this database" in a smaller context.
Apart from the attribution thing, the excerpted database is not different, legally, from the "mother database"; there is nothing in ODbL that refers to that mother database in any way.
