This shows that during the currently ongoing audit, the memory card in the vote counting machine being audited was cleared before running the election audit.
This would likely have the effect of wiping out any modifications performed on that card intended to effect the election. In other words, you could rerun the election and it would function normally because any modifications intended to influence the election would be wiped out.
Does it prove there was anything nefarious? No. But is it intended to prevent future auditors from discovering if there was anything nefarious? I can't think of other serious explanations, but I'm not an expert on how these machines work or exactly what each machine command on the tape means.
But it sure looks like the "auditors" in New Hampshire got caught deleting election records and potentially evidence of a crime.
UPDATE: It's possible the card being cleared was not an actual card used in the election. It could be a copy, or even an entirely new card with fresh programming. So that's one possible explanation.
UPDATE: There's also some date manipulation that seems significant.
