Are imported unbalanced Payables invoices supposed to hit Correct Import Errors?

We've noticed that unbalanced Payables invoices make it past the Import Payables Invoices ESS job successfully and then when validated, end up with Needs Revalidation status.

The question is: should unbalanced Payables invoices land in Correct Import Errors instead or is this a bug?

Background - we're importing invoices using OIC from our source systems and we noticed that some invoices make it through and we can find them in Manage Invoices but they are sitting in Needs Revalidation status. When we check them, we find that the invoice header amount and sum of the invoice line amounts are mismatched.
