There is also a difference between "six" and "half-a-dozen" objects, but that difference is not one detectable by a count of the objects. No one disagrees that there may be a difference to some in perception, since there is a difference in the words and thus the sound of the two terms.
I have asked you to provide the LEGAL difference in consequences between CPP Article 530.1 and 530.2 acquittals for not having committed the crime (act), and if I understand correctly, you have not provided any such difference.
Here is an English translation of the text of the article; I have rearranged the text of Article 530.1 compared to my source in order to provide parallel construction.
CPP Article 530 Judgment of acquittal
1. The judge shall deliver a judgment of acquittal, mentioning the cause in the operative part of the judgment, if
the criminal act did not occur,
the accused did not commit it,
the act was not deemed an offence by by law or
it was committed by a person who cannot be accused or punished for a different reason.
2. The judge shall deliver a judgment of acquittal also in case of insufficient, contradictory, or lacking proof that
the criminal act occurred,
the accused committed it,
the act is deemed an offence by law,
the offence was committed by a person with mental capacity.
3. The judge shall deliver a judgment of acquittal under paragraph 1 if there is proof that
the underlying causes of the committed act are either a reason for justification or
a personal reason for exemption from punishment or
there is doubt on the existence of such reasons.
4. By means of the judgment of acquittal, the judge shall apply the security measures, in the cases provided for by law.

Note that in the US, the term "insufficient evidence" generally means:
Evidence so inadequate that a court will find that the prosecution or plaintiff has no basis upon which to proceed, and will most likely dismiss the case.

n. a finding (decision) by a trial judge or an appeals court that the prosecution in a criminal case or a plaintiff in a lawsuit has not proved the case because the attorney did not present enough convincing evidence. Insufficient evidence usually results in dismissal of the case after the prosecution or the plaintiff has completed his/her introduction of evidence or, if on appeal, reversal of the judgment by the trial court.

ETA: Whether an acquittal is attributed to CPP Article 530.2 (as by the Marasca CSC panel in the final, definitive judgment) or to Article 530.1 (as by the Hellmann court in their acquittal), there must still be a motivation report in accordance with Italian law and constitution. And the motivation report for each judgment details the reasoning for the judgment, and should be relied upon for insights into that reasoning as the court wished to present it.
