The last A test undoes the modifications and brings the vehicle back to the same condition it was in when doing the control test. This should confirm the original A test data. If it does not, then some condition has changed which should cause the B test to be questioned.
An example of why the second A test could be significantly skewed is changing wind conditions. If the wind changed during testing, then the B data is invalid.
