There have been many posters in the past that claim that a chess program is it's opening book, it's engine, and it's tablebases (if it has them), and not just it's engine. If you take the opening book away, the program plays at a lesser ability. Following that thought, if you improve upon the opening book, the program plays at a greater ability (maybe not much, but some). This is not necessarily a bad thing, but the GM will be playing against Hiarcs 7+, not Hiarcs 7. This will still indicate whether a chess program can beat a GM in match play, it just is not an indication of whether Hirarcs 7 can beat a GM in match play. It will be a tweaked version (regardless of whether Matt tweaks the opening book, or Hiarcs 7 does). I do agree with you that this will still be a valid test of Hiarcs 7's engine strength, with the caveat that if the GM finds a way to force Hiarcs into a certain line which is losing for the computer in even one game due to the GMs practicing against the computer (i.e. the computer falls into a deterministic, for the computer, set of bad positions), then the GM has merely tricked the program and did not really play it.
