Invoice Validation and profile "AP:Maximum Invoice Validation Child Requests"

Hi - we're using R12.1.3

We have an issue with Invoice Validation taking a long time to run and I am investigating whether we can start to use the functionality described in this Note:

R12: New Functionality Invoice Validation Parallel Processing (Doc ID 1917614.1)
https://support.oracle.com/rs?type=doc&id=1917614.1

Currently the "AP:Maximum Invoice Validation Child Requests" profile is not set on our system.

I wanted to get a better understanding of how this functionality works.

This is what our Invoice Validation parameters look like at the moment:

Looking at an example scenario - if there are 1,000 invoices to validate, and the "AP:Maximum Invoice Validation Child Requests" profile is set to 2, and the Max Invoices Count is set to 100, does that mean that 2 child jobs run in parallel at a time, each validating 100 invoices - and when each has done 100 invoices, it ends, and another kicks off - so there would be 10 child jobs in that example?
