Reading between the lines....
He was checking something that had happened on the test.
Students will swear blind that they were taught to do certain exercises certain ways. Which may be not the way the examiner wants them done.
If he hasn't seen the product from a school/instructor before he will have been giving you the benift of the doudt that its the school balls up not yours.
After a couple of tests from an instructor they know if your fibbing and don't bother asking.
If it turns out you have been telling fibs it will turn into a fail instead of a debrief point.
An example of this is in the stalling exercises with, if you have to stick the nose at the deck or various points inbetween, hanging the air fannying about lifting wings with the rudder etc. Where the reality is its a unload until the aircraft unstall's while applying power. On the incipent stalls you have people teaching power out with no change in attitude to sticking the nose at the deck. If they find out that the school is teaching the wrong method the CAA gets informed if its a school wide thing or the CFI will have a word in the instructors ear and it gets sorted out.
