Credit Check Rules

We have a credit check rule set up that I'm testing a change. We want to implement Overide Manual Release. If I understand the use correctly setting the days to 2 orders that were manually released should go back on hold after two days? Is this correct or would something need to change on the order (price, billing information etc) to re-trigger the credit check?

We also are looking into the use of AME with the credit hold release to set up approvals per dollar values but I have not found any information on if this can be done.
