Review Comment:
Could we add a case where the filter results in nothing being deleted?

Review Comment:
Is it possible to separate these into 2 test methods, one for no stats and
the other with stats? Could we also update the messages to be more precise,
instead of just "Should not match: nested column", I think "isNull nested
column should not match"
