Enforce Processing of Costs by Transaction Date

In Cost Profiles, we have the accounting rule "Enforce Processing of Costs by Transaction Date", which, as I understand, ensures that transactions are processed in chronological order based on the Transaction Date, for the same item and valuation unit combination.

For example, if a transaction dated April 10 is unprocessed, then a later transaction dated April 15 for the same item and valuation unit will also not be processed until the April 10 transaction is resolved.

My question is:
If both the April 10 and April 15 transactions have already been successfully processed, and a new transaction is later entered with an earlier Transaction Date
