API server 'Filters for object selection' what does it do, and how does it work?

About this configuration feature in the API server going by the name 'Filters for object selection what does it do, and how does it work?
I tried to configure this feature leaving me a bit confused...

One Identity Manager Administrator Portal: Configuration > Web Portal > Three-dots icon > Create configuration key

Filters for object selection
Specify filter conditions (WHERE clauses) for foreign key columns. Enter column names in the format "<Table name>.<Column name>" (e.g. "MyTable.FirstColumn"). To refer to base object values, use the "%ColumnName%" syntax and to refer to the identifier of the current user, use the "%useruid%" variable.

Filters for object selection by table
(Specify filter conditions (WHERE clauses) for foreign key columns. Enter table names in the format "<TableName>" (e.g. "MyTable"). To refer to base object values, use the "%ColumnName%" syntax and to refer to the identifier of the current user, use the "%useruid%" variable.)

I configured the following:

Filters for object selection / Person.IsTemporaryDeactivated (PropertyConfig/FkWhereClausesByColumn/Person)
%IsTemporaryDeactivated% = 0

Filters for object selection by table / Person (PropertyConfig/FkWhereClausesByTable/Person)
%IsTemporaryDeactivated% = 0

The config file: inetpub\wwwroot\ApiServerDev\bin\CCC.CompositionApi.global.json
{"Scopes":[{"AppliesTo":"portal","Ignore":false,"Data":{"PropertyConfig/FkWhereClausesByTable/Person":"%IsInActive% = 0","PropertyConfig/FkWhereClausesByColumn/Person":"%IsInActive% = 0"}}],"AppliesTo":null,"Ignore":false,"Data":null}

Logged in with a user that is manager of some accounts and has the following application role: Identity Management\Identities\Administrators
I couldn't see any difference all the temporary deactivated identities where still visible under "My Direct Reports" and in the "Data Explorer\Identities"

Changed the value of 'PropertyConfig/FkWhereClausesByTable/Person' without the %%

Filters for object selection by table / Person (PropertyConfig/FkWhereClausesByTable/Person)
IsTemporaryDeactivated = 0

Did didn't change much only the following URL returned a filtered response:
itshop.groot.net/.../candidates

API server logging:
Classification risk: 0, fp: , hash: , trusted hash: , already checked: False, tries: 0, last try: - ago, where clause: (isnull(IsInActive, 0) = 0) and (IsTemporaryDeactivated = 1)

When I rolled back to the original value: %IsTemporaryDeactivated% = 0
The log showed this:
Classification risk: 0, fp: , hash: , trusted hash: , already checked: False, tries: 0, last try: - ago, where clause: (isnull(IsInActive, 0) = 0) and (0 = 0)
