To repeat my point Pawel - I think you're reading too much into this. It's an example, not fully representative.
But yes, it's quite normal to list in a plan a nominal flight that something will be done. Then it won't actually happen that way - a planned flight may be split into three for reasons of repetition or non-delivery, or two combined, or something not quite completed and then the missing tests tagged onto another flight. This is normal in the conduct of flight testing.
It IS normal in reporting that flights will have numbers, and post flight reports use those numbers, and a tests and conditions completion grid will then show the flight numbers on which particular data were obtained. This is the flight numbers that really matter, not some nominal plan for which flight will carry which tests, written ahead of time.
Remember the adage by a Roman General "No plan of action ever survives contact with the enemy". The same is absolutely true of flight test plans.
