Performing Rollups and Repeated Queries

[branderson-js]

In the example for Avoid Repeated Queries it is shown being used in the Before Insert Context.

However, if I want to leverage a query like this:

Parent_Object__c[] sObjectList= [
                SELECT Id,Rollup_Field__c,
                (SELECT Field_To_Rollup__c FROM Child_Object__c)
                FROM Parent_Object__c
                WHERE Id IN :parentObjectIds
            ];

The sub-query results won't include the most recent inserts to the DB in the beforeInsert context.

So my question is, would I have to create two TAF Custom Metadata records, one for before in your example and one for after like I am trying to achieve with each sub-class implementing the corresponding TriggerAction interface?
