It is applied at the same time, since it is a circular
definition. You take the proposed set of final sets
and test if they comply. If you test {B, C} it passes.
If you test {A} it also passes. (Assuming no existential
import in the definition.) Therefore, there is no well
defined set of final clubs, as there are two competing
suitable and incompatible candidates.

Both things.

Yes, when it gives a single set of final clubs. But not when
more than one set is possible.

If what you object to is the vacuous satisfaction of
the definition by A, then use this new definition for
well defined final sets:

      Final sets are all sets with some preclusion.

In your example, the situation is one where B and C
are well defined final sets. To prove my new definition
wrong you need a situation where a club with some
preclusion is not final.
