Yes that is what it does. Unbound also attempts to refresh and fetch
the new correct value for the record, every time it is asked. That
should bring the record back to the correct value. Once it is available
to be fetched.
That makes the 0 value possible as a default, it is used until a better
value becomes available.
Best regards, Wouter
